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。
Heck coupling method for the first time synthesized a new hole containing the hole transport unit 3-dodecylthiophene and electron transport unit 1,3,4-oxadiazole low bandgap energy poly 2,4-divinyl-3 - dodecylthiophene-1,3,4-oxadiazole conjugated polymer (P3DDTV-OXD). The synthesized copolymers were characterized by 1H-NMR, FT-IR, gel chromatography (GPC), UV-vis spectroscopy, fluorescence spectroscopy (PL) and cyclic voltammetry (CV). Compared with the regular poly-3-dodecylthiophene homopolymer (P3DDT), the copolymer showed a blue shift in UV maximum absorption wavelength and P1 maximum emission wavelength with strong blue fluorescence and a high electron affinity , At the same time has the hole and electron transport capacity, to achieve a two-way charge transfer within the molecule.
