合成了萘酞菁锌,利用傅立叶红外光谱、元素分析和MALDI-TOF质谱等手段表征了分子结构;循环伏安测试和吸收光谱确认了共轭体系的扩大使分子带隙下降.根据材料加工性能的不同,分别采用溶液法、层-层蒸镀(Layer—by—layer evaporation)法和单层分散旋涂法,将给体分子萘酞菁锌与三种受体分子1-(3-甲氧基羧基)丙基-1-苯基-[6,6]C61,C60和N,N'-二嘧啶基花四羧基二酰亚胺进行了复合,通过研究复合前后荧光变化,确认了给体-受体两相界面处发生了由分子能级差引发的光致电荷转移,为制备更宽光伏响应范围的太阳能电池器件提供了潜在的新途径.
Naphthalocyanine zinc (ZnNc) was synthesized and its molecular structure was characterized by FT-IR, elemental analysis, and MALDI-TOF mass spectrum. Cyclic voltammetry and optical absorption spectra confirmed that the extension of the conjugated system reduced the band gap of ZnNc compound. The composites of ZnNc with three electron acceptors of N,N'di[2'-pyrimidinyl]-3,4,9,10-perylenetetracarboxylic diimide, C60, and 1-(3-methoxycarbonylpropyl)-l-phenyl[6,6]C61 were prepared by solution-blending, layer-by-layer evaporation, and spin-coating, respectively. The fluorescence quenching of the composites indicated that the photo-induced charge transfer occurred due to the energy level offset between the ZnNc and acceptor molecules.
