Quality Control of Bis[2-(1-isoquinolinyl-N)phenyl-C](2,4-pentanedionato-O2,O4)iridium(III). Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. 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 Chemically doped hole transporting materials with low cross-linking temperature and high mobility for solution-processed green/red PHOLEDs. Author is Wang, Jingxiang; Liu, Hongli; Wu, Sen; Jia, Yi; Yu, Hang; Li, Xianggao; Wang, Shirong.

Recently, developing insoluble cross-linkable functional layers plays a vital role for solution-processed organic light emitting diodes (OLEDs). Here, 2 vinyl-based cross-linkable hole transporting materials V-TPAVTPD and V-TPAVCBP are designed and synthesized. Cationic photoinitiator 4-octyloxydiphenyliodonium hexafluoroantimonate (OPPI) is 1st introduced to chem. induce vinyl-based photo crosslinking process, aiming at lowering crosslinking temperature and enhancing hole mobility. Crosslinking can occur at expressly low temperature of 120° with >95% solvent resistance. Hole mobility is markedly enhanced with the value >10-3 cm2 V-1 s-1. When applying hole transporting layers (HTLs) to solution-processed green and red phosphorescent OLEDs, devices exhibit excellent properties. The maximum current efficiency of 54.0 cd A-1 (green), 9.8 cd A-1 (red) and external quantum efficiency of 15.5% (green), 15.0% (red) are obtained when OPPI doped V-TPAVCBP serves as HTL. This low temperature feasible crosslinking process to prepare HTLs with preferable hole mobility promotes the development of OLEDs.

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 Gate Tunable Organic Light Emitting Diodes: Principles and Prospects, published in 2019, which mentions a compound: 435294-03-4, mainly applied to gated organic light emitting diodes composite electrodes; composite electrodes; electrolytes; gated organic light-emitting diodes; porous electrodes; work function tunable electrode, Quality Control of Bis[2-(1-isoquinolinyl-N)phenyl-C](2,4-pentanedionato-O2,O4)iridium(III).

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.

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. 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 Nanoscale Mapping of Morphology of Organic Thin Films, the main research direction is 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.Computed Properties 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.

The host in phosphrescent organic light emitting devices (PhOLEDs), showing the thermally activated delayed fluorescence (TADF) charateristic, can effectively overcome the efficiency roll-off. Herein, six bipolar compounds with donor-π-acceptor (D-π-A) and D-π-A-π-D structures have been synthesized using 1,2,4-triazole derivative (TAZ) as an acceptor and phenothiazine (PTZ), phenoxazine (PXZ), and 9, 9-dimethylacridane (DMAC) as donors. The mol. structures were confirmed by 1H NMR, 13C NMR and X-ray single-crystal diffractions. The large steric hindrance endows these mols. with typical TADF features, including the small singlet-triplet energy splitting (ΔEST) of 0.08-0.30 eV and completely spatially sep. highest occupied MOs (HOMO) and the lowest unoccupied MOs (LUMO) electron densities. The PhOLEDs hosted by these novel TADF materials display excellent performances with low efficiency roll-off.

Tetra-chromatic (Blue-Green-Red-Orange) white organic light-emitting diodes (WOLEDs) with superior color stability was demonstrated. Strong carrier trapping effects of red dyes cause significant color shift in multi-color WOLEDs. The high color stability here is attributed to the decrease of red dye trapping sites and enhancement of effective energy transfer to red dye while maintaining appropriate exciton concentration near red dye. As luminance increased from 1000 to 10000 cd m-2, variations in Commission Internationale de L’Eclairage are merely (0.007, 0.007). Furthermore, this color-stable WOLED achieved a color rendering index close to 90 simultaneously.

Safety of Bis[2-(1-isoquinolinyl-N)phenyl-C](2,4-pentanedionato-O2,O4)iridium(III). The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. 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 Achieving High Electroluminescence Efficiency and High Color Rendering Index for All-Fluorescent White OLEDs Based on an Out-of-Phase Sensitizing System. Author is Liu, Hao; Chen, Jinke; Fu, Yan; Zhao, Zujin; Tang, Ben Zhong.

Sensitizing conventional fluorescence (CF) dopants with thermally activated delayed fluorescence (TADF) materials has achieved considerable progress, by which the advantages of TADF materials and CF dopants can be fully harnessed. However, the usually used co-phase configuration of CF dopant-engaged sensitizing systems often encounters exciton loss due to Dexter energy transfer (DET). Herein, an effective out-of-phase configuration is proposed to sensitize CF dopants in the fabrication of white organic light-emitting diodes (WOLEDs). Based on a new efficient sky-blue TADF luminogen DCP-BP-DPAC which has an electroluminescence (EL) peak at 486 nm and an EL efficiency of 26.6%, a green TADF material BDMAC-XT, and a red CF dopant DBP sensitized by BDMAC-XT through an out-of-phase configuration without interlayer, efficient WOLEDs are successfully fabricated. By further adopting orange TBRB or 4CzTPNBu as intermediate sensitizers, more efficient energy transfer to DBP is achieved via Forster energy transfer. Through step-by-step energy transfer and elimination of excess DET process, high-performance all-fluorescent WOLEDs are achieved, providing excellent EL efficiencies over 23.0%, and highly stable white light with a high color rendering index of 87. The outstanding EL performance and high-quality emission color demonstrate the great potential of the proposed out-of-phase design for sensitizing systems of WOLEDs.
