A novel coordination polymer, named [Cd(HCOO)(pbpy)_0.5(bdc)(H₂O)]·3H₂O (1), based on a new flexible viologen ligand 1,1′-[1,4-phenylenebis(methylene)]-bis(4,4′-bipyridinium) dichloride (pbpy·2Cl), Cd(NO₃)₂·4H₂O and terephthalic acid (H₂bdc) was synthesized. Compound 1 has good photosensitive activity and can also respond to sunlight at room temperature. And using time-dependent density functional theory (TDDFT) to study the discoloration mechanism of compound 1. Attractively, 1 has the ability to select and detect amines due to the electron-deficient properties of pbpy·2Cl. In addition, photocontrolled luminescence properties of 1, during the coloration-decoloration process, has been researched.

一种基于新型柔性紫罗碱配体1,1'-[1,4-亚苯基双的新型配位聚合物，命名为[Cd(HCOO)(pbpy) _0.5 (bdc)(H ₂ O)]·3H ₂ O ( 1 ) (亚甲基)]-双(4,4'-联吡啶)二氯化物( pbpy·2Cl )、Cd(NO ₃ ) ₂ ·4H ₂ O和对苯二甲酸(H ₂ bdc)的合成。化合物1具有良好的光敏活性，在室温下对阳光也有反应。并利用时变密度泛函理论(TDDFT)研究了化合物1的变色机理。有吸引力，1由于pbpy·2Cl的缺电子特性，具有选择和检测胺的能力。此外，已经研究了在着色-脱色过程中1的光控发光特性。
