一、引言从1948年以来,陆续发现许多具有巨大共轭体系的有机化合物呈现类似半导体的特性,近来高分子半导体的合成则使这领域的研究工作进入了一个新的阶段。同时,在催化领域中则早已证明,许多优良的催化剂,如某些金属的氧化物,硫化物等都是典型的无机半导体,并且发现这些半导体的电学性质,如电导率,功函数等与其催化性质之间有着密切的联系。在这一基础上发展起来的半导体催化作用的电子理论已经成为催化理论的主要方向之一。因此,很自然地会想到,有机半导体是否也具有与无机半导体类似的催化 I. INTRODUCTION Since 1948, many organic compounds with huge conjugated systems have been found to exhibit semiconductor-like properties. Recently, the synthesis of polymer semiconductors has led to a new phase of research in this area. At the same time, it has long been proven in the field of catalysis that many excellent catalysts, such as oxides and sulfides of certain metals, are typical inorganic semiconductors and the electrical properties of these semiconductors such as conductivity, work function, etc., There is a close relationship between nature. The electronic theory of semiconductor catalysis developed on this basis has become one of the main directions of catalytic theory. Therefore, it is quite natural to think whether organic semiconductors also have similar catalysis as inorganic semiconductors
