摘要: 用L-B膜方法在SnO2电极上修饰了不同链长烷氧基取代的酞菁锌化合物(ZnPc CnH2n+1,n=3,9,12,16),分别研究了它们单分子膜成膜性能和转移性能,并测定了修饰在SnO2电极上的单多层分子膜的光电性能和吸收光谱。研究结果指出链短的取代基即异丙氧基取代的酞菁锌(ZnPcC3H7(i))具有较高的转移比及较好的光电性能。

Abstract: The SnO2 electrodes were modified by phthalocyanine with different length of alkyl substitutes (ZnPcCH2n+1,n=3,9,12,16) using L-B method. The formation of a stable monolayer on water and the characterics of phase transition were observed. The photovoltaic behaviours and adsorption spectra of monolayer assemblies were determined. The results showed that L-B films of ZnPcC3H7(i) which has horter chain of alkyl substitutes exhibit larger transfer ratio and better photovoltaic effects.
