Abstract

Three lanthanide-based coordination polymers (Ln-CPs) with layered structure, {[La2(L)3(DMF) (H2O)3]·H2O}n(1), {[Eu2(L)3(DMF)2(H2O)]·(H2O)}n(2) {[Tb2(L)3(DMF)2(H2O)]·H2O}n(3) were successfully synthesized from H2L(N,N′-bis(4-carbozylbenzyl)aniline). Remarkably, compound 3has extremely high sensitivity to 4-nitrophenol. When the concentration of 4-nitrophenol reaches 5.98 × 10−3 mmol/L, the fluorescence intensity of compound 3is quenched by 59%. The calculated KSVis 7.56 × 104and limit of detection (LOD) is 4.73 μg/L. 3exhibits a highly sensitive detection towards Fe3+and compound 2shows outstanding antibacterial effects on Staphylococcus aureus, respectively. The white light emission was also investigated by changing the mixing ratio of LaNO3, EuNO3and TbNO3during the preparation of coordination polymers.

Abstract

Three novel 3D coordination polymers (CPs), {[Cd(L)(bimb)](H2O)4}n (1), {[Zn(L)(bibp)](H2O)(DMF)}n (2) and {[Zn(L)(bif)](H2O)4}n (3) (bimb = 1,4-bis(imidazoly-1-yl)benzene, bibp = 4,4′-bis(imidazol-1-yl)biphenyl, bif = 2,7-bis(1-imidazoly)fluorene, H2L = 1-(4-carboxylphenyl)piperidine-4-caboxylic acid) have been synthesized under solvothermal conditions. Compound 1 featured a 5-fold interpenetration of the 4-c dia net. Compound 2 and 3 presented a 6-fold interpenetration of the 4-c dia net. Moreover, their luminescence properties and the selective detection of Fe3+ ion for 1 were investigated. In addition, the adsorption ability of 1 and 2 toward dye molecules was tested, respectively. Furthermore, their ECL behaviors were tested. [ABSTRACT FROM AUTHOR]
