This article reports a novel coordination polymer based on a new flexible viologen ligand, and investigates its photosensitivity and photocontrolled luminescence properties.
A novel coordination polymer, named [Cd(HCOO)(pbpy)(0.5)(bdc)(H2O)].3H(2)O (1), based on a new flexible viologen ligand 1,1'[1,4-phenylenebis(methylene)]-bis(4,4';-bipyridinium) dichloride (pbpy.2Cl), Cd (NO3)(2).4H(2)O 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.
