| 摘 要： | 采用Heck偶合法首次合成了新型的含有空穴传输单元3-十二烷基噻吩和电子传输单元1,3,4-噁二唑的低带隙能的聚2,4-二乙烯基-3-十二烷基噻吩-1,3,4-噁二唑共轭聚合物(P3DDTV-OXD).并且通过1H-NMR、FT-IR、凝胶色谱(GPC)、UV-vis光谱、荧光光谱(PL)、循环伏安(CV)法对所合成的共聚物进行了分析表征.与规整的聚3-十二烷基噻吩均聚物(P3DDT)相比,共聚物的UV最大吸收波长和Pl最大发射波长明显蓝移,具有强烈的蓝色荧光,且电子亲和势较高,同时拥有空穴和电子传输能力,实现了电荷在分子内的双向传输.

| Abstract: | The novel low band gap conjugated polymer,which consisted of an electron-donating 3-dodecylthiophene unit and an electron-accepting 1,3,4-oxadiazole unit,was synthesized through Heck Couple approach.The obtained copolymer was effectively characterized using 1H-NMR,FT-IR,gel permeation chromatography(GPC),UV-vis spectroscopy,photoluminescence(PL),as well as cyclic voltammetry(CV).Compared to regioregular poly(3-dodecylthiophene) homopolymer,the UV-vis maximum absorption and Pl maximum emission wavelength of ... |
