Synthesis of Chiral Coordination Polymers by Spontaneous Resolution

Three complexes have been synthesized from the reactions of 3,3-tetramethyleneglutaric acid (H2TMG), Cd(NO3)2,
and secondary ligands:  [Cd(TMG)]n (1), {[Cd(TMG)(1,10-phen)·H2O]·2H2O}n (2), and [Cd(TMG)(4,4‘-bipy)]n (3) (phen = 1,10-phenanthroline, 4,4‘-bipy = 4,4‘-bipyridine). By adopting potential chiral ligands, metal−organic helical chains as a transmitter for
chiral information, and coordination bonds as chiral discriminative interactions, the chiral coordination polymer 3 with an interesting
three-dimensional architecture has been synthesized successfully by spontaneous resolution.

以3,3-四亚甲基戊二酸（H2TMG）、硝酸镉（Cd(NO3)2）与辅助配体为反应底物，通过配位反应合成了三种配合物：[Cd(TMG)]ₙ（1）、{[Cd(TMG)(1,10-菲咯啉（1,10-phenanthroline）)·H₂O]·2H₂O}ₙ（2）以及[Cd(TMG)(4,4’-联吡啶（4,4‘-bipyridine）)]ₙ（3）。其中phen指代1,10-菲咯啉，4,4’-bipy指代4,4’-联吡啶。本研究通过选用潜在手性配体、以金属有机螺旋链作为手性信息传递载体，并以配位键作为手性识别相互作用，经自发拆分过程成功合成了具有独特三维结构的手性配位聚合物3。
