Poly(2,7-di-n-pentyldibenzofulvene)s with no stereocenters, obtained by anionic polymerization using chiral 9-fluorenyllithium ligand complexes, showed intense circular dichroism in film form due purely to the chiral conformation of the main chain, while no chiroptical properties were detectable in solution.
无立体中心的聚(2,7-二-n-戊基二苯并呋喃烯)通过使用手性9-荧光基锂配合物的阴离子聚合获得,在薄膜形式中表现出强烈的圆二色性,这纯粹归因于主链的手性构象,而在溶液中未检测到手性光学特性。
