摘要:
Provided is an organic electroluminescent device that exhibits an efficient host-dopant energy transfer mechanism, and thus, expresses a certain high-efficiency electroluminescent performance, based on improved electron density distribution. The organic electroluminescent device also overcomes low initial efficiency and short operation life property, and secures high-performance electroluminescent performance with high efficiency and long life property for each color.
摘要:
Disclosed are a novel thiazole-containing benzophenone derivative represented by formula 1, and an isomer thereof, a pharmaceutically acceptable salt thereof, a hydrate thereof and a solvate thereof, a pharmaceutical composition comprising the derivative, a use of the derivative as therapeutic agent and a method for preparing the derivative. The benzophenone thiazole derivatives inhibit formation of microtubules and eliminate actively proliferating cells of malignant tumors to control general cell proliferation. In formula 1, R, R1 and R2 are defined as above.
