54231-32-2 - Reference Information
| Uses | 3-chloro-2-nitropyridine is a pharmaceutical intermediate that can be used to prepare a pharmaceutical composition for the treatment of osteoarthritis and a diazacarbazole derivative used in the field of organic electroluminescence. |
| Preparation | There are reports in the literature that 3-chloro-2-nitropyridine can be prepared from 3-amino-2-nitropyridine through continuous flow reaction. 3-chloro-2-nitropyridine can be used to prepare a diazacarbazole derivative. Carbazole compounds have sufficiently high triplet state, good hole transport ability, photochemical stability, high carrier mobility, strong absorption in the ultraviolet light range and a band gap of about 3.20eV, and valuable blue light And other characteristics, replace and modify on the 3,6,9-position or other carbon atoms to obtain a variety of high-efficiency luminescent materials. The luminescent material obtained by bonding the carbazole-like group diazacarbazole with different groups with electron-deficient properties can also realize the triplet state and adjustable molecular orbital energy level of the material. So as to fundamentally realize the efficient recombination of carriers in organic electroluminescent devices and obtain efficient and energy-saving OLED devices. It can also be widely used in the field of organic electroluminescence. |
