ABSTRACT
A series of fluorescent coordination polymers (CPs) {[Cd2(CH3-bpeb)2(BDC)2] CP1, (BDC)0.5/(NH2-BDC)0.5-CP1, (BDC)0.34/(NH2-BDC)0.66-CP1, (BDC)0.25/(NH2-BDC)0.75-CP1, (BDC)0.2/(NH2-BDC)0.8-CP1, (NH2-BDC)-CP1} were prepared from conjugated ligand 4,4'-((2-methyl-1,4-phenylene)bis(ethene-2,1-diyl))bipyridine (CH3-bpeb), terephthalic acid (BDC), aminoterephthalic acid (NH2-BDC) and CdSO4 under solvothermal conditions. The fluorescence of aqueous suspensions of these CPs was quenched by folic acid (FA) in a concentration dependent manner. The efficiency of quenching increasing with an increased proportion of NH2-BDC ligand in the CP with (NH2-BDC)-CP1 exhibiting a low detection limit of 1.7 × 10-7 M.
