Simple molecular structure design of iridium(III) complexes: Achieving highly efficient non-doped devices with low efficiency roll-off

To construct efficient emitters suitable for non-doped devices and deeply understand the relationship between structures and performances, we designed and synthesized two heteroleptic iridium(III) complexes based on 1,2-diphenyl-1H-benzoimidazole (PBI) li

High-performance and stable warm white OlEds based on orange iridium(III) phosphors modified with simple alkyl groups

Phosphorescent organic light-emitting diodes (OLEDs) with high electroluminescence (EL) efficiency and low efficiency roll-off are urgently required to meet the continuously increasing market need in lighting industry fields. There is an urgent demand for

Sublimable cationic Ir(iii) phosphor using chlorine as a counterion for high-performance monochromatic and white OLEDs

Different from the previous design strategy, herein, a cationic Ir(iii) complex ([(ptbi)2Ir(bisq)]Cl) with a small chlorine as the counterion was synthesized, which realized the formation of a solid film via a vacuum-deposition process. The whi

Synthesis of some fluorescent benzimidazole derivatives using cobalt(ii) hydroxide as highly efficient catalyst-spectral and physico-chemical studies and ESIPT process

Some fluorescent benzimidazole derivatives have been designed and synthesized using cobalt(ii) hydroxide as highly efficient catalyst. Synthesized compounds have been characterized by 1H and 13C-NMR and mass spectral analysis. The so

Aerobic Copper-Catalyzed Synthesis of Benzimidazoles from Diaryl- and Alkylamines via Tandem Triple C-H Aminations

Through radical-induced tandem triple C-H aminations with free amines as the aminating agents, we herein present a precedent on aerobic copper-catalyzed synthesis of 5-diarylamino benzimidazoles, a class of optoelectronic device analogues by combining two molecules of diarylamines and one molecule of alkylamine in one single operation. The developed chemistry proceeds with the merits of a natural abundant copper/O2 catalyst system, readily available feedstocks, broad substrate scope, good functional group tolerance, exclusive regio- and chemoselectivity, high step and atom efficiency, which offers an important basis for further construction of functional products that are inaccessible or difficult to prepare with the existing methods by employing catalytic tandem C-H amination strategy.

Small-molecular OLED electron transport material and preparation method and application thereof

The invention belongs to the technical field of organic electron transport materials, and relates to a small-molecular OLED electron transport material and a preparation method and an application thereof. Compounds of the small-molecular OLED electron transport material comprise an aromatic fused heterocycle and an aryl-substituted benzimidazole group which are connected with each other. The two kinds of groups not only enable the compounds to have good electron accepting capability, but also tend to planarity to be beneficial to molecular stacking, and are beneficial to combination of holes and electrons and exciton generation, so that the electron mobility of the material is improved, and the device efficiency is improved; meanwhile, the combination of the two enables carrier transmission to be balanced; when the small-molecular OLED electron transport material is applied to an organic light-emitting device and used as an electron transport layer, the device shows the advantages of low driving voltage and high light-emitting efficiency, and is superior to an existing common OLED device.

Transition-Metal-Free Synthesis of 1,2-diphenyl-1H-benzo[d] Imidazole Derivatives from N-phenylbenzimidamides and Cyclohexanones

A transition-metal-free strategy for the formation of 1,2-diphenyl-1H-benzo[d] imidazoles from N-phenylbenzimidamides and cyclohexanones is introduced. This is the first report on the direct synthesis of 1,2-diphenyl-1H-benzo[d] imidazoles from cyclohexanones and N-phenylbenzimidamides via iodine- promoted oxidative cyclization. Non-aromatic cyclohexanones were smoothly dehydrogenated, and acted as an aryl source using oxygen as a green oxidant. The catalytic use of iodine makes this method quite simple, more economical and convenient. Under optimized conditions, various substituted 1,2-diphenyl-1H-benzo[d] imidazoles were smoothly reacted, and the desired substituted imidazoles were generated with moderate to excellent yields. (Figure presented.).
