摘要:
苯乙烯和4- 氯甲基苯乙烯共聚得到侧链部分氯甲基化的聚苯乙烯( PSt - CH 2Cl) , 氯甲基的含量由1H NMR 和元素分 析确定。另外以4- 甲氧基苯甲酸为原料, 经多步反应合成4- ( 5- 苯基- 1, 3, 4- 噻二唑- 2- 基) 苯酚( PTP) 。在四氢呋 喃溶液中, PT P 和PSt- CH 2Cl 在碱作用下发生醚化反应, 得到侧链含2, 5 - 二苯基- 1, 3, 4 - 噻二唑聚合物, 聚合物溶液 的荧光激发光谱显示激发峰为259 nm 和366 nm; 荧光发射光谱显示在370- 500 nm 处有很强的荧光。通过循环伏安法测得阳 极和阴极的启动电位计算出聚合物的HOMO 和LUMO 分别为- 6.34 eV 和- 2.90 eV, 带隙Eg 为3?? 44 eV, 而紫外光谱测得 的光学带隙E g 为3.38 eV ( λo nse t367 nm ) 。
