Two Chemically Stable Cd(II) Polymers as Fluorescent Sensor and Photocatalyst for Aromatic Dyes
Two new 2D Cd(II)-based coordination polymers (CPs), viz. [Cd(2)(H(2)L)(2)(2,2’-bipy)(2)] (1) and [Cd(L)(0.5)(phen)·0.5H(2)O] (2), have been constructed using ethylene glycol ether bridging tetracarboxylate ligand 5,5′(4,4′-phenylenebis(methyleneoxy)) diisophthalic acid (H(4)L). Both CPs behaved as...

description | Two new 2D Cd(II)-based coordination polymers (CPs), viz. [Cd(2)(H(2)L)(2)(2,2’-bipy)(2)] (1) and [Cd(L)(0.5)(phen)·0.5H(2)O] (2), have been constructed using ethylene glycol ether bridging tetracarboxylate ligand 5,5′(4,4′-phenylenebis(methyleneoxy)) diisophthalic acid (H(4)L). Both CPs behaved as profound fluorescent sensor for Fe(3+) ion and nitro-aromatics (NACs), specifically 2,4,6-trinitrophenol (TNP). The stability at elevated temperature and photocatalytic behaviors of both 1 and 2 for photo-decomposition of aromatic dyes have also been explored. An attempt has been made to explore the plausible mechanism related with the decrease in fluorescence intensity of 1 and 2 in presence of NACs using theoretical calculations. Additionally, the probable mechanism of photo catalysis by 1 and 2 to photo-degrade aromatic dyes has been explained using density of states (DOS) calculations. |
