将外消旋苯乙炔与脂肪酶进行动力学拆分，将带有光学活性羟基或酯基的苯乙炔共聚，合成光学活性螺旋聚苯乙炔；通过用非手性大异氰酸酯或酰基氯对羟基进行进一步化学修饰，螺旋方向从一种螺旋反转为另一种螺旋。
An optically active helical poly(phenylacetylene) was synthesized by the copolymerization of phenylacetylenes bearing optically active hydroxy or ester groups obtained by the kinetic resolution of a racemic phenylacetylene with lipase; the helix-sense was inverted from one helix to another by the further chemical modification of the hydroxy groups with achiral bulky isocyanates or an acid chloride.
