在聚（苯基异氰酸酯）末端引入一个单一的手性取代基与可切换的构象平衡允许使用各种外部刺激的聚合物主链的螺旋感的控制。通过多米诺效应实现螺旋义增强，其中螺旋义通过VCD光谱和DFT计算来指定。
The introduction of a single chiral substituent with a switchable conformer equilibrium at the poly(phenyl isocyanate) terminus allowed the control of the helical sense of the polymer backbone using various external stimuli. Helical sense enhancement was achieved through a domino effect, where the helical sense was assigned by VCD spectroscopy and DFT calculations.
