Use of Cadmium Inclusion Complex for the Preparation of Crystalline CdS Materials

Abstract

Inclusion complex, [Cd(phen) 2 (H 2 O) 2 ]2L·6H 2 O (1), where HL= 4-methylbenzenesulfonic acid and phen = phenanthroline, could be achieved by combining d 10 Cd 2+ to HL and small organic molecule phen in high yield under moderate conditions. Nanoparticles of CdS could be obtained by hydrothermal decomposing single crystals of 1 with the assistance of Na 2 S. We found that the various solvents contribute very little to the shape of outcome CdS. But in the presence of sodium hydroxide, regular CdS crystals could be obtained successfully. The structures have been characterized by scanning electron microscopy and powder X-ray diffraction.
