- Electron transport material and organic light emitting device thereof
-
The invention discloses an electron transport material and an organic light emitting device thereof, and relates to the technical field of organic photoelectric materials. On the one hand, a benzimidazole group has a very good rigid planar structure and stability; on the one hand, an azacarbazole group has a high triplet energy level (2.96 eV) and a stable energy level, wherein an unsaturated C=Ndouble bond enhances the electron transporting ability; on the other hand, the benzimidazole group combines with the azacarbazole group to increase a conjugated system, a continuous pi-conjugated system brings better electron mobility, thereby having a high electron mobility, due to a large energy gap and the high electron mobility of a compound, the injection of electrons can be effectively ensured, the effect of blocking holes is achieved, and the material can be used as hole blocking materials and electron transporting materials. The material can be applied to the organic light-emitting device, and the device has advantages of low driving voltage and high luminous efficiency, and is superior to existing conventional OLED devices.

- Discovery of novel, orally available benzimidazoles as melanin concentrating hormone receptor 1 (MCHR1) antagonists
-
Melanin concentrating hormone (MCH) is an important mediator of energy homeostasis and plays role in several disorders such as obesity, stress, depression and anxiety. The synthesis and biological evaluation of novel benzimidazole derivatives as MCHR1 antagonists are described. The in vivo proof of principle for weight loss with a lead compound from this series is exemplified.
