Synthesis of Two Coordination Polymer Photocatalysts and Significant Enhancement of Their Catalytic Photodegradation Activity by Doping with Co 2+ Ions
The coordination polymers (CPs) [Zn 2 (tipm)(1,3‐BDC) 2 ] ( 1 ) and [Co 2 (tipm)(1,3‐BDC) 2 ] · 0.5CH 3 CN ( 2· 0.5CH 3 CN) were synthesized by the reactions of Zn(NO 3 ) 2 or Co(NO 3 ) 2 with tetrakis[4‐(1‐imidazolyl)phenyl]methane (tipm) and benzene‐1,3‐dicarboxylic acid (1,3‐H 2 BDC) under solvot...
