When the molecular weight of polymers was low, the oligomer cannot adopt stable helicalconformation;
结果表明,当分子量较低时,聚合物不能形成稳定的螺旋结构;

Moreover, the stability of helicalconformation of poly (phenylacetylene) decreased with the increasing temperature.
聚苯乙炔螺旋构象的稳定性随着温度的提高而降低。

In general, bulky side-chain and hydrogen bonding are in favor of the formation of stable helicalconformation for polymers, which endows them with high optical property and some special performance.
