报道了两种具有不同网络结构的杯[4]-双硫杂冠醚配位聚合物的温度依赖性组装。在除去配位溶剂分子后，初始溶剂配位聚合物经历独特的单晶到单晶的转化为去溶剂化的聚合物。在溶剂配位和去溶剂化聚合物中观察到的结构特征也揭示了相关的溶剂化光致发光“关-开”行为。
The temperature-dependent assembly of two 3-D Cul coordination polymers containing calix[4]-bis-thiacrown with different networking motifs are reported. Upon removal of the coordinated solvent molecules the initial solvent-coordinated polymer undergoes a unique sing le-crystal-to-single-crystal transformation to the desolvated polymer. Structural characteristics observed in the solvent-coordinated and the desolvated polymers also reveal related solvato-photoluminescence "off-on" behavior.
