Homochiral Silver-Based Coordination Polymers Exhibiting Temperature-Dependent Photoluminescence Behavior

Homochiral coordination polymers based on zigzag or helical polymers are assembled from a semiflexible fluorescent bipyridyl ligand and linear coordinated AgI ions; they exhibit unusual temperature-dependent photoluminescence behavior, including multistep changes in energy and intensity upon cooling.以半柔性荧光联吡啶配体与线性配位银(I)离子为构筑基元，组装得到以锯齿状或螺旋状聚合物为骨架的同手性配位聚合物；该类材料展现出异常的温度依赖性光致发光特性，具体表现为冷却过程中发光能量与强度的多步变化。
