Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. 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 Highly Efficient Deep Blue Aggregation-Induced Emission Organic Molecule: A Promising Multifunctional Electroluminescence Material for Blue/Green/Orange/Red/White OLEDs with Superior Efficiency and Low Roll-Off. Author is Xu, Zeng; Gu, Jiabao; Qiao, Xianfeng; Qin, Anjun; Tang, Ben Zhong; Ma, Dongge.

For the constant demand of organic light-emitting diodes (OLEDs) with high efficiency, long lifetime, and low cost for display and lighting applications, the development of high-performance organic electroluminescence materials is key. Aggregation-induced emission (AIE) luminogens (AIEgens) provide a promising choice for their excellent performance in nondoped devices. A multifunctional deep blue AIE material, which can be used not only as an excellent blue emitter but also as a good host of green/orange/red phosphors, is reported. A deep blue nondoped OLED with a CIEy of 0.08 and high external quantum efficiency (EQE) of 7.0% is achieved. Green/orange/red phosphorescent OLEDs with high efficiency and low roll-off are obtained. Hybrid white OLEDs (WOLEDs) based on the deep blue AIEgen exhibit simultaneously high CRI (>90), excellent efficiency (EQEmax> 25%, PEmax = 99.9 lm W-1 for 2-color WOLEDs, PEmax = 60.7 lm W-1 for 4-color WOLEDs), low roll-off (PE1000nit = 72.1 lm W-1 for 2-color WOLEDs, PE1000nit = 43.5 lm W-1 for 4-color WOLEDs), and superior stable color, indicative of the multifunction of AIEgens. Accordingly, this work opens a new direction for achieving high-performance OLEDs, particularly offering a smart but simple way to depress the efficiency roll-off and reduce the cost of OLEDs for practical applications.

The charge-transport property is one of crucial factors to determine the performance of the polymer-based devices. The hole-transport properties of regioregular poly(3-hexylthiophene-2,5diyl) (P3HT) and [6,6]-Ph C61-butyric acid Me ester (PCBM) blends with two blend ratios were investigated using transient electroluminescence (EL) measurements. For EL, organic light emitting diodes are fabricated with P3HT:PCBM blends as hole-transport layers. To reduce absorption, a red phosphorescent emitter with bis(1-phenylisoquinolinato-N,C2′) iridium(acetylacetonate) [(piq)2Ir(acac)] was used. Transient EL with red color is obtained in spite of P3HT:PCBM absorption and hole mobilities of P3HT:PCBM layers are calculated using delay times in transient EL signals. The hole mobility of pristine P3HT:PCBM with 1:0.8 blend ratio is approx. 6.2 x 10-5 cm2 V-1 · s-1 at approx. 615 kV cm-1, and it decreases when the PCBM ratio increases. The hole mobility of the P3HT:PCBM layer increases to approx. 1.07 x 10-4 cm2 V-1 · s-1 at approx. 615 kV cm-1 when the P3HT:PCBM blend is thermally annealed.

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.

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.

So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Wu, Yuling; Li, Xuefeng; Zhao, Haocheng; Li, Jie; Miao, Yanqin; Wang, Hua; Zhu, Furong; Xu, Bingshe researched the compound: Bis[2-(1-isoquinolinyl-N)phenyl-C](2,4-pentanedionato-O2,O4)iridium(III)( cas:435294-03-4 ).HPLC of Formula: 435294-03-4.They published the article 《Pyrene-based hyperbranched porous polymers with doped Ir(piq)2(acac) red emitter for highly efficient white polymer light-emitting diodes》 about this compound( cas:435294-03-4 ) in Organic Electronics. Keywords: bisphenylisoquinolineacetylacetonate iridium red emitter pyrene polymer PLED. We’ll tell you more about this compound (cas:435294-03-4).

Here, we designed and prepared a series of hyperbranched porous polymers constructed using fluorene branches and pyrene core, and all hyperbranched porous polymers exhibit intense blue fluorescence, good morphol. stability, and high thermal stability. Further, it is found that the aperture sizes for hyperbranched porous polymers can be adjusted by simply changing the content of pyrene and fluorene in the synthesis process. When the feed ratios of pyrene in the total polymers is 15 mol%, the optimized aperture size was obtained, which is slightly larger than the maxlength of complementary red emitter Bis(1-phenylisoquinoline)(acetylacetonate)iridium (III) (Ir(piq)2acac), indicating the Ir(piq)2acac can well distributed in the apertures of hyperbranched porous polymers in co-doped film of Ir(piq)2acac and hyperbranched porous polymers. The fabricated polymer-light-emitting diode (PLED) with such co-doped film as light-emitting layer realizes good white emission with almost equal blue and red emission intensity from hyperbranched porous polymers and Ir(piq)2acac. The balanced electroluminescent (EL) spectra contribute to ideal Commission Internationale de l’Eclairage (CIE) coordinate of (0.326, 0.374) located at white light zone. In addition, the device also achieves high device performance with maximum luminance and current efficiency reaching 5369 cd/m2 and 8.35 cd/A, resp. We believe that such porous-structure polymers have huge potential applications in the development of highly efficient white PLEDs with reducing production cost.

Color-tunable white organic light-emitting diodes (CT-WOLEDs) having daylight chromaticity and a wide correlated color temperature (CCT) span can mimic our circadian cycle and realize application for lighting or decoration. The effects of the recombination zone and energy distribution on the electro-optical properties and color span are investigated in this paper. We find that it is beneficial to expand the CCT span by increasing the distance between the red ultrathin phosphorescent emissive layer and the center of the recombination zone. By increasing the concentration (y) of mCP in mixed host material in the emitting layer and the thickness (z nm) of the red ultrathin phosphorescent emissive layer, the CCT spans can be expanded towards high CCT and low CCT, resp. The widest CCT span reaches 4032 K (2391-6423 K) in a simple all-phosphorescent CT-WOLED with a maximum luminance and power efficiency of 9249 cd m-2 and 15.35 lm W-1, resp.

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 An Amorphous Spirobifluorene-Phosphine-Oxide Compound as the Balanced n-Type Host in Bright and Efficient Light-Emitting Electrochemical Cells with Improved Stability. Author is Tang, Shi; Larsen, Christian; Rafols-Ribe, Joan; Wang, Jia; Edman, Ludvig.

A rational host-guest concept design for the attainment of high efficiency at strong luminance from light-emitting electrochem. cells (LECs) by suppression of exciton-polaron quenching [Tang et al., Nature Communications 2017, 8, 1190] has been reported. However, a practical drawback with the presented host-guest LEC devices was that the operational stability is insufficient for many applications. Here, a systematic study is performed, revealing that a major culprit for the limited operational stability is that the employed n-type host, 1,3-bis[2-(4-tert-butylphenyl)-1,3,4-oxadiazo-5-yl]benzene (OXD-7), has a strong propensity for crystallization and that this crystallization results in a detrimental phase separation of the constituents in the active material during device operation. The authors, therefore, identify an alternative class of concept-functional n-type hosts in the form of spirobifluorene-phosphine-oxide compounds, and report that the replacement of OXD-7 with amorphous 2,7-bis(diphenylphosphoryl)-9,9′-spirobifluorene results in a much improved operational lifetime of 700 h at >100 cd m-2 during constant-bias driving at an essentially retained high current efficacy of 37.9 cd A-1 and a strong luminance of 2940 cd m-2.
