We successfully synthesized optically active polymer 4 by using chiral bisphosphine, (S,S)-1,2-bis(boranato(t-butyl)methylphosphino)ethane (SS)-1, as a key building block. The structure of the polymer was characterized by H-1, C-13, and P-31 NMR spectra. According to the CD spectra, the p-phenylene-ethynylene unit in the polymer main chain exhibited Cotton signals around the area of pi-pi* transition band.
