摘要
A novel imidazole derivative, 2-(4-(2,5-dibutoxy-4-vinyistyryl)phenyl)-4,5-diphenyl-1H-imidazole) (VPDPI), as optoclectronic material was designed and synthesized by heck coupling reaction. The structure, thermal analysis and photoluminescence (PL) properties were investigated. The results indicate that the organic compound has good PL property. The emission peak of VPDPI is in the blue regions (465 tun), and the luminescence quantum yield is 0.61 in ethanol, which show that the compound emits blue light and is a desirable blue-emitting photoluminescence material. Also the organic compound shows better thermal stability due to the molecular structure introduced by imidazole heterocyle. The compound can be polymerized for the design of novel and efficient organic optoelectronic materials.
