摘要：
There is disclosed an optically active polysilane represented by the following general formula:
wherein R 1 and R 2 are a combination of (R)-3,7-dimethyloctyl group and (S)-3-methylpentyl group, R 3 is an alkyl group having 3 to 20 carbon atoms and formed of a branched structure which is branched at any one of the first to fourth carbon atoms positioned away from the backbone chain, R 4 is a straight-chain alkyl ether group having 2 to 22 carbon atoms, or a straight-chain alkyl group having 2 to 22 carbon atoms, x is a number ranging from 0.01 to 0.99, and n is a number ranging from 10 to 100,000.
