摘要

采用Wittig-Horner反应合成了叔丁基苯咔唑衍生物。核磁共振氢谱、红外光谱、质谱和元素分析等表征手段对产物的化学结构进行了确认。利用紫外吸收光谱仪、荧光发射光谱仪、热重分析仪、示差扫描量热仪和电化学工作站对这些化合物的光物理性能、热性能和电化学性能进行了初步表征。实验结果表明：所合成的化合物无论在溶液状态还是固体状态均能发射强烈荧光；化合物具有较高的溶液荧光量子产率(77%～54%)；它们的能隙较窄，约为2.9 eV；在紫外吸收光谱和荧光发射光谱上，化合物的最大吸收和发射波长与连接基团有明显的关系；合成的产物均具有非常高的热稳定性，热失重5%的温度(T

)超过470 ℃，玻璃化温度(T

)超过220 ℃。所合成的化合物可望成为高性能发光材料应用于发光器件。

Abstract

The novel

tert

-butylphenyl carbazole derivatives were synthesized by WittigHorner reactions. The chemical structures of the derivatives were determined by

H NMR

MS and EA analyses

and their properties were investigated by UV

TGA

DSC and CV methods. The results showed that ① the synthesized compounds could emit strong fluorescence either in solutions or in solid states and their fluorescent quantum yields ranged from 77% to 54%; ② the compounds possessed high thermal stabilities

and their thermal decomposition temperatures and glass transition temperatures were higher than 470℃ and 220 ℃

respectively;③ their maximum absorption and fluorescence emission wavelengths were related to the linking groups.
