A coordination polymer with guest-molecule-based luminescence is flexible in preparation and shows greater controllability. A one-dimensional chain coordination polymer CdL has been synthesized by in situ hydrolysis of 2,6-pyridinedicarboxylic acid monomethyl ester and cadmium nitrate. Although the coordination polymer does not exhibit a three-dimensional structure, each chain piles up to form penetrating diamond channels. Based on the functionalities and size effect of the crystal channels, fluorescein, rhodamine 6G and Ru(bpy)₃Cl₂ can be dispersed into the channels through encapsulation experiments of a series of luminescent molecules and complexes. It shows good dual-emitting performance and proves that we have successfully introduced guest molecules to regulate the luminescence performance of CdL.

新型Cd(II)-吡啶甲酸酯配位聚合物的合成及主客体发光性能研究

具有客体分子发光的配位聚合物制备灵活，可控性更强。2,6-吡啶二甲酸单甲酯与硝酸镉原位水解合成了一维链配位聚合物CdL。虽然配位聚合物没有呈现出三维结构，但每条链都堆积起来形成穿透的金刚石通道。基于晶体通道的功能和尺寸效应，荧光素、罗丹明 6G 和 Ru(bpy) ₃ Cl ₂可以通过一系列发光分子和配合物的封装实验将其分散到通道中。它显示出良好的双发光性能，证明我们成功地引入了客体分子来调节 CdL 的发光性能。
