摘要

设计合成了以哌嗪为电子给体，2，2'： 6'，2"-三联吡啶为电子受体的超分子聚合物构筑单元PPTPY，通过Zn

、Cd

诱导自组装聚合，得到相应的金属超分子聚合物PPTPY-Zn和PPTPY-Cd，并通过核磁共振对其结构进行了确认。紫外-可见吸收光谱研究表明，在

，

-二甲基乙酰胺(DMAc)溶剂中，其最大吸峰位置相对于聚合前分别红移了74nm和59nm，聚合物PPTPY-Zn和PPTPY-Cd的固态膜荧光发射峰在549nm和552nm，且半峰宽为lllnm和113nm，荧光颜色表现为橙光发射。循环伏安性质研究表明，单体和聚合物均表现出明显的氧化峰，PPTPY-Zn和PPTPY-Cd的起始氧化电位分别为0. 75V和0. 79V，均低于PPTPY的 0. 84V。

Abstract

The monomer PPTPY with piperazine as electron donor and 2

2’:6'2"-terpyridine as electron acceptor was synthesized. Via Zn

and Cd

-directed self-assembly polymerization

the metallo-supramolecular polymers PPTPY-Zn and PPTPY-Cd were obtained. And their structures were determined by NMR. The UV absorption spectra of PPTPY-Zn and PPTPY-Cd showed red shifted 74nm and 59nm respectively in comparison to building block monomer PPTPY in DMAc solution. And the emission maxima of PPTPY-Zn and PPTPY-Cd films are at 549nm and 552nm with half-peak width of 111nm and 113nm

which exhibited orange emission

in films respectively. The cyclic voltammogram showed that the onset oxidative potential of PPTPY-Zn and PPTPY-Cd were 0. 75V and 0. 79V

both of that were lower than that of 0. 84V for PPTPY.
