Abstract
There is disclosed a method for producing organoplatinum polymers by reacting 5,6,11,12-tetradehydrodibenzo a,e!cyclooctenes with platinum complexes. The organoplatinum polymer thus obtained has .pi.-coordinated acetylene in the main chain, and is expected to be used as electronic materials, nonlinear optical materials, and polymer platinum complex catalysts, that can be used in air.
