中文摘要： 超分子聚合物是基于弱相互作用形成的一类聚合物，本项目基于配位作用展开，合成了一系列含芴单元及含DCM单元的以三联吡啶修饰的超分子构筑单元，将不同构筑单元在过渡金属离子的诱导作用下进行组装，形成基于配位作用的超分子聚合物/共聚物。通过不同供电基团的引入，合成了含电子给体-受体（D-A）的超分子构筑单元，并设计出星型单元，由这些D-A结构组成的超分子聚合物均表现出对溶剂极性的强烈依赖性。共聚物的性能对于两种单元的比例有较强依赖性，在490-610nm之间呈现宽泛的双峰发射。Zn2+、Cd2+金属离子介入的超分子聚合物，表现出较强的荧光发射性质，而Ru2+介入后对室温荧光有淬灭作用，但表现出更强的配位作用，所得到的聚合物显示出优异的氧化还原性质，在+1.25eV呈现可逆氧化还原峰，且该类聚合物在310-405nm范围内呈现出较强的吸收峰。

英文摘要： Supramolecular polymer is the polymer which is based on weak interaction. In this study, a serials of building blocks containing fluorene and DCM was synthesized and, induced by the transition metal ion, the supramolecular polymers/copolymers which is based on coordination were formed. Through introduction of different electron-donation structures, the building blocks containing D-A unit were synthesized and the star-shaped structure was obtained. The resulting supramolecular polymers which are based D-A building blocks exhibit obvious dependence on the polarity of the solvent. The properties of supramolecular copolymers depend on the ratio of two building blocks heavily, and the polymers exhibit broad double-peaks emission at 490-610 nm. The supramolecular polymers containing Zn2+ and Cd2+ show strong emission and the introduction of Ru2+ causes the emission quench at room temperature but better coordination ability. In addition, the Ru2+-induced polymers showed reversible redox peaks at about +1.25 eV and the strong absorption bands at 310-405 nm were been observed.
