Abstract
In this study, we describe the synthesis of four Lead based organic frameworks (1-4) using 2,5-thiophenedicarboxylic acid (H2TDC) and 4-mercaptobenzoic acid (H(2)MBA) as organic linkers. Lead nitrate and Lead acetate were used as source of Pb+2 ions. The morphological and other structural aspects of these MOFs were subsequently established on the basis of Fourier transform infrared spectroscopy (FTIR), H-1 NMR, Scanning electron microscopy (SEM), thermogravimetric analysis (TGA) and powder x-ray diffraction technique. Brunauer-Emmett-Teller (BET) studies of these MOFs (1-4) revealed more promising adsorption of N-2 gas by MOF 1 (surface area, 3699 m(2)g(-1)) followed by 3 (surface area, 742 m(2) g(-1)), 4 (surface area, 382 m(2) g(-1)), 2 (surface area, 318 m 2 g -1 ). Moreover, these MOFs (1-4) have been investigated for their luminescence activity assigned to ligand-to-metal charge transfer (LMCT).
