A chiral harvesting transmission mechanism is described in poly(acetylene)s bearing oligo(p-phenyleneethynylene)s (OPEs) used as rigid achiral spacers and derivatized with chiral pendant groups. The chiral moieties induce a positive or negative tilting degree in the stacking of OPE units along the polymer structure, which is further harvested by the polyene backbone adopting either a P or M helix.

使用寡聚（对苯乙炔）作为间隔基在螺旋聚（乙炔）衍生物中收集手性信息

描述了一种手性收获传递机制，其带有寡聚（对亚苯基乙炔基）（OPE），用作刚性非手性间隔基并用手性侧基衍生。手性部分在沿着聚合物结构的 OPE 单元堆叠中诱导正或负倾斜度，该倾斜度通过采用P或M螺旋的多烯主链进一步收获。
