N-(3,5-二乙炔基苯甲酰基)-L-丙氨酸十二烷基酰胺1与具有吡啶、联吡啶和菲咯啉配体2a-2d的氯化铂(Pt)进行脱氯化氢偶联聚合，得到主链上带有Pt的新型光学活性聚(亚苯基乙炔基)[聚(1-2a)-聚(1-2d)]。聚合物的 Z 平均直径范围为 453 至 1081 nm。 Poly(1-2a) 表现出可归属于聚集体的 CD 信号，并形成高度为 540 ± 70 nm、节距为 62 ± 6 nm 的调节扭曲结构，这通过 AFM 测量得到证实。
The dehydrochlorination coupling polymerization of N-(3,5-diethynylbenzoyl)-l-alanine dodecylamide 1 with platinum (Pt) chlorides having pyridine, bipyridine, and phenanthroline ligands 2a–2d gave novel optically active poly(phenyleneethynylene)s [poly(1-2a)–poly(1-2d)] bearing Pt in the main chains. The Z-average diameters of the polymers ranged from 453 to 1081 nm. Poly(1-2a) exhibited CD signals assignable to aggregates, and formed regulated twisted structures with height of 540 ± 70 nm and pitch of 62 ± 6 nm, which were confirmed by AFM measurements.
