| 摘 要： | 合成了PCPDTBT,通过NMR,GPC等方法对聚合物进行了表征.研究了聚合物的热学与电化学性质.采用溶液法将电子给体PCPDTBT与两种电子受体1-(3-甲氧基羰基)丙基-1-苯基6,6]C61(PCBM)和ZnO纳米粒子分别进行了复合,通过研究复合前后的荧光变化,确认了给体-受体两相界面间发生了由分子能级差引发的光致电荷转移.这些研究结果为探索性能更佳的有机太阳能电池材料体系提供了重要的参考依据.

| Abstract: | Poly2,6-(4,4-bis-(2-ethylhexyl)-4H-cyclopenta2,1-b;3,4-b]dithiophene)-alt-4,7-(2,1,3-benzothiadiazole)] (PCPDTBT) is a new kind of low band-gap polymers for applications in organic photovoltaic devices.However,PCPDTBT was studied as the donor to form the photoactive composites only with organic acceptors (fullerene derivatives) so far.In this article,PCPDTBT was synthesized,and its chemical structure,thermal stability and energy levels were identified and characterized by NMR,GPC,TGA,and CV,respectively.F... |
