中文摘要： 在无机/有机复合半导体材料的光电转换器件研究中, 存在的问题主要是体异质结光电转换过程、光生载流子再复合及其向电极的输运等。对于上述问题，一般是通过调控微相分离尺度、微相结构、电子结构来解决。理论上,可以利用金属离子与特殊官能团(-NH2; -COOH)的相互作用或有机盘状分子间的π-π组装诱导作用来调节复合材料的结构与性质。故申请者拟以溶液法制备系列硫属化合物、系列具有氨基或羧基基团的酞菁衍生物、苝酰亚胺衍生物的二元或多元无机/有机功能复合材料。通过改变有机溶剂、材料结构、薄膜制备工艺、后处理工艺等方法来调节复合材料体系中的形貌、微相分离尺度、微相结构和电子结构。并选择适当材料体系用于太阳能电池、光电探测器、场效应晶体管、光催化等方面的研究，同时探索一种低成本制备无机/有机功能复合薄膜的新方法。

英文摘要： The photoelectric conversion process of bulk heterojunction, the recombination of photogenerated charge carriers and transport to the contacted electrode are keys to scientific problems in a photoelectric converting device of the oragnic /inoragnic coupled semiconductors. Generally, the control of the scale and structure of micro-phase separation and electronic structure can solve these problems. In the theory, the structure and properties of the composites can regulate by the interaction between metal ions and specific groups (-NH2; -COOH) of organic discoid molecules, and the inducing effect of π-π assembly of oragnic discoid molecules. The applicant proposed that binary or multiple inorganic / organic functional composite materials, which were composed by a series of chalcogenides、phthalocyanine derivatives and perylene bisimide derivatives , were prepared using polar solvent in this project. The morphology，the scale of micro-phase separation, micro-phase structure and electronic structure of the composite system were regulated by changing the organic solvent, the organic material structure, preparation process of thin film, post-processing technology and other methods. Then, we select a appropriate materials system used for the research of solar cells, photoelectric detector, field effect transistor and photocatalysis, and explore a kind of low cost new method for preparation of inorganic/organic composite film.
