PURPOSE: To obtain an organic semiconductive polymer having a polyene structure and being excellent in electric conductivity, photoconductive properties, etc., and suitable for use in photo-electric conversion elements, by hydrogeneting the main chain of a specified polydiacetylene with a hydrogenative reducing agent.
CONSTITUTION: The purpose organic semiconductive polymer having repeating units of formula V is obtained by hydrogenating a polymer having repeating units of formula I or II (wherein R is a group of formula III or IV) with a hydrogenative reducing agent. The hydrogenative reducing agents which can be suitably used include, for example, (n-C4H9)3SnH, Raney nickel, AlH(i-C4H9)2, Lindlar catalyst and Ti(CO)2(C2H5)2. In this way, the main chain of the polydiacetylene can be converted into a polyene structure, which results in increased electric conductivity and improved photoconductive properties of the polymer.
