Synthesis and Optoelectronic Properties of Novel Binaphthyl Derivatives

以咔唑和4,4'-二氨基-1,1'-联萘为初始原料,经重氮化反应、Ullmann反应、NBS亲电取代反应和Suzuki偶联反应,合成了两种新型空穴传输材料——4,4'-双[(9-对甲基苯基)-9H-3-咔唑基]-1,1'-联萘(4a)和4,4'-双[(9-对联苯基)-9H-3-咔唑基]-1,1'-联萘(4b),其结构经1H NMR和元素分析表征。研究了4a和4b在二氯甲烷中的UV和荧光性质。结果表明,4a和4b的最大发射波长分别为429 nm和427 nm。

Two novel hole-transporting materials, 4＇-bis I [ 9-（p-tolyl） ]-gH-3-carbazole I-1,1 ＇- bi- naphthyl （ 4a ） and 4,4＇-bis I [ 9- （biphenyl-4-yl） ] -gH-3-carbazole } -1,1 ＇- binaphthy! （ 4b ）, were synthesized from carbazole and 4,4＇-diamino-1,1 ＇- binaphthyl by diazo reaction, UUmann reaction, NBS electrophilic substitution and Suzuki cross-coupling reaction. The structures were characterized by 1H NMR and elemental analysis. Optoelectronic properties of 4a and 4b were investigated by UV and PL. The results showed that λmax of 4a and 4b were 429 nm and 427 nm, respectively.
