Two novel bipolar hosts Cbz-Py-PQ and Cbz-Py-SA have been designed, synthesized, and eventually successfully used for fabrication of red phosphorescent organic light-emitting diodes (PhOLEDs). Considering higher hole mobility than that of electron mobility in most of the bipolar host with 1:1 donor: acceptor ratio, herein we have made it 1:2 by linking carbazole (donor core) to pyrroloquinoxaline/benzothiadiazine 1,1-dioxide (acceptor core) through pyridine (acceptor core) featuring donor-acceptor-acceptor (D-A-A) architecture. Structure-property-performance relationship have been realized through evaluation of thermal, photophys. and electrochem. properties of both the mols. Cbz-Py-PQ hosted red PhOLED revealed maximum efficiencies of 16.4%, 9.6 cd A-1 and 9.4 lm W-1 with maximum luminance of 20753 cd m-2 at 11.0 V.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Nanoscale Mapping of Morphology of Organic Thin Films, published in 2020-11-11, which mentions a compound: 435294-03-4, mainly applied to organic thin film morphol nanoscale mapping depth resolution; luminescent dye sensor mol transition dipole moment orientation; Fourier plane imaging microscopy; dipole orientation; microscopy; morphology; nanoscale; organic; van der Waals solid, Synthetic Route of C35H27N2O2Ir.

We determine precise nanoscale information about the morphologies of several organic thin film structures using Fourier plane imaging microscopy (FIM). We used FIM microscopy to detect the orientation of mol. transition dipole moments from an extremely low d. of luminescent dye mols., which we call “”morphol. sensors””. The orientation of the sensor mols. is driven by the local film structure and thus can be used to determine details of the host morphol. without influencing it. We use sym. planar phosphorescent dye mols. as the sensors that are deposited into the bulk of organic film hosts during the growth. We demonstrate morphol. mapping with a depth resolution to a few Ångstroms that is limited by the ability to determine thickness during deposition, along with an in-plane resolution limited by optical diffraction. Furthermore, we monitor morphol. changes arising from thermal annealing of metastable organic films that are commonly employed in photonic devices.

This record summarizes our recent developments on gate-tunable organic light-emitting diodes (OLEDs). The key point is to modulate the charge carrier injection barrier by the applied gate potential. One way is to electrochem. dope charge carrier injection layer through porous electrodes. The electrochem. doped charge carrier layer thus form gate-tunable contact with porous electrodes. Another way is to modulate the work-function of electrodes that can have varied charge carrier injection barriers following the applied gate potential. Gate-tunable OLEDs based on these two working principles have been fabricated, characterized and demonstrated for displaying simple digitals and letters. New materials including dielec., porous electrodes, work function tunable electrodes, and charge carrier injection materials have been further explored for performance improvement.

Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 435294-03-4, is researched, Molecular C35H27N2O2Ir, about The width of exciton formation zone dominates the performance of phosphorescent organic light emitting diodes, the main research direction is phosphorescent organic light emitting diode current efficiency.Product Details of 435294-03-4.

Abstract: Phosphorescent organic light emitting diodes (PHOLEDs) have been fabricated with structure of indium tin oxide/MoO3 doped 4,4′-N,N’-dicarbazole-biphenyl (CBP) 30 nm/tris(4-carbazoyl-9-ylphenyl)amine 10 nm/CBP doped with tris(2-phenylpyridine)iridium(III) (CBP:Ir(ppy)3) x/bathocuproine 50 nm/LiF 1 nm/Al, where x = 2.5, 5, 10, and 20 nm, resp. The current efficiency (CE) of device with x = 10 nm is higher than those with x = 2.5 and 5 nm, mostly because the width of exciton formation zone (5.7 nm) with x = 10 nm is larger than those (2.5 and 5 nm) with x = 2.5 and 5 nm. However, the c.d. with x = 10 nm decreases than those with x = 2.5 and 5 nm at a certain driving voltage, since the ∼ 4.3 nm CBP:Ir(ppy)3 accommodating no exciton formation with x = 10 nm plays a role of transporting holes, raising ohmic loss of hole and thereby increasing driving voltage. When x increases from 10 to 20 nm, the width of exciton formation zone rises from 5.7 to 6.8 nm with CE almost unchanged, and the c.d. decreases as a result of increased ohmic loss of hole. The current research is useful to develop high-efficiency and low-driving voltage PHOLEDs.

Currently, exciplex has drawn a great deal of attention due to its potential for efficient electroluminescence and for use as a host. In this study, we used 4,4′,4″”-Tris(carbazol-9-yl) triphenylamine (TCTA) and 1,3,5-Tri(m-pyridin-3-ylphenyl) benze nee (TmPyPB) to form an exciplex host, where Bis[2-(4,6-difluorophenyl)pyridinato-C2,N](picolinato)iridium(III)(FIrpic) was used as the dopant to emit blue phosphorescent light. Addnl. FIrpic and Bis(1phenylisoquinoline) (acetylacetonate) iridium(III) emission layers were inserted in the proposed structure to investigate how the recombination area of carriers shifts with the increase of voltage. TCTA and non-doped FIrpic layers were then inserted in both sides of the emission layer to confine the carriers, and the thickness of the emission layer was also optimized to improve the current efficiency of the proposed devices. The efficiency of the devices was increased from 56 cd/A to 63.6 cd/A with the addnl. quantum well structure and an emission layer thickness of 15 nm. The current efficiency reported in this paper was fairly high as compared with other published data on blue-emission exciplex-based organic light-emitting diodes. In addition, the device with the quantum well structure exhibited purer blue-light emission, and the color temperature stability was also highly improved.

Now I present to you an article called Dual-emitting nanocomposites for oxygen-carrying capacity analysis and boosted singlet oxygen generation in stored red blood cells, published in 2019-12-31, which mentions a compound: 435294-03-4, mainly applied to conjugated polymer nanoconjugate oxygen detection red blood cell, Related Products of 435294-03-4.

We combined the unique natural oxygen transporting function of red blood cells (RBCs) with photosensitive nanocomposites to create biomaterials with strong singlet oxygen (1O2) generation. During cold storage for a long time, structural changes to RBCs may occur, which reduce their oxygen carrying capacity. The nanocomposite developed herein featured dual emission characteristic, which enabled evaluation of the status of the RBCs. On the basis of energy transfer from the conjugated polymer to iridium(III) complexes, the formed nanocomposites show intense, long-lived and oxygen-sensitive emission. When modified with 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[methoxy(polyethyleneglycol)-2000], the nanocomposites non-invasively entered RBCs through hydrophobic interactions. We measured the quenching effect of oxygen on the emission of the iridium(III) complexes. The differential fluorescent signals and fluorescence lifetime images indicated the storage history of the RBCs. RBCs in good condition stored oxygen. When engineered with nanocomposites, RBCs generated large amounts of cytotoxic 1O2 upon irradiation These decorated RBCs might serve as a new kind of photosensitive biomaterial.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: Bis[2-(1-isoquinolinyl-N)phenyl-C](2,4-pentanedionato-O2,O4)iridium(III), is researched, Molecular C35H27N2O2Ir, CAS is 435294-03-4, about White organic light emitting diodes based on localized surface plasmon resonance of Au nanoparticles and neat thermally activated delayed fluorescence and phosphorescence emission layers.Formula: C35H27N2O2Ir.

White organic light emitting diodes (WOLEDs) incorporating gold (Au) nanoparticles (NPs) beneath PEDOT:PSS hole injection layer (HIL) and employing neat blue DMAC-DPS(B) and green 4CzIPN(G) thermally activated delayed fluorescence (TADF) emission layer (EML) together with sandwiched ultrathin red phosphorescence Ir(piq)2(acac)(R) EML have been fabricated and the effects of the localized surface plasmon resonance (LSPR) of Au NPs and EML thickness on the electroluminescence (EL) performance are investigated. It is found that EML thickness imposes vital influence on the EL performance of the WOLEDs and the WOLEDs with the embedded Au NPs and simple EML structure with optimal thickness of G(15 nm)/R(0.3 nm)/B(15 nm) demonstrate maximum power efficiency (PE), external quantum efficiency (EQE) and color rendering index (CRI) around 11.73 lm/w, 10.51% and 94, indicating the achievement of balance between EL efficiency and CRI by carefully adjustment of EML thickness with the presence of Au NPs. Furthermore, the LSPR effects from the Au NPs on the EL efficiency and CRI have been clearly demonstrated. Especially the green and red light emission is dramatically enhanced leading to enormous improvement of CRI, which can be ascribed to the remarkable enhancement of energy transferring inside G(15 nm)/R(0.3 nm)/B(15 nm) EML proved by the much shortened decaying lifetime at 475 and 550 nm from transient photoluminescence(PL) decaying testing. Almost double enhancement of the total fluorescence efficiency (including prompt fluorescence (PF) and delayed fluorescence (DF)) at 550 nm can be obtained with the assistance of LSPR from Au NPs, which increase from 23.85% to 49.82% and 15.22%-28.86% for resp. EML of G(15 nm)/B(15 nm) and G(15 nm)/R(0.3 nm)/B(15 nm). The decaying dynamics including the DF, PF, phosphorescence (PH) and energy transferring inside G(15 nm)/R(0.3 nm)/B(15 nm) EML with and without embedded Au NPs is discussed in details. The study provides an easy way to utilize the LSPR of Au NPs together with simple neat TADF and phosphorescent EML to develop high quality WOLEDs.

Extremely stable white emission out of a hybrid white quantum dot-organic light-emitting diode (WQD-OLED) was achieved by developing a novel concept of device architecture. The new inverted device structure employs a thermally-evaporated red phosphorescent emitting layer (EML) with an n-type modulation and a multi-stacked hole transporting layer (HTL) on the top of solution-processed ZnO nanoparticles for an electron transporting layer and blue and green QD-mixed EML. The multi-stacked HTL, tris(4-carbazoyl-9-ylphenyl)amine (TCTA)/1,1-bis[(di-4-tolylamino)phenyl]cyclohexane (TAPC), and the n-type modulation layer, 2,2′,2′′-(1,3,5-benzinetriyl)-tris(1-phenyl-1-H-benzimidazole) (TPBi) successfully balanced low-mobility holes with high-mobility electrons, and uniformly distributed the charges across the blue/green QD and red EMLs. In particular, the role of the n-type modulation layer was comprehensively analyzed with impedance spectroscopy and verified to minimize the undesired Auger recombination by excess charges and broaden the recombination zone. Consequently, highly stable white emission (0.32 ± 0.02, 0.31 ± 0.02) in CIExy color coordinates over 4 V operating voltage range (or two decades of c.d.), 3.92% external quantum efficiency, and 3.83 h device lifetime at 500 cd m-2 up to 50% of the initial luminance (LT50) were simultaneously obtained.
