Abstract
This report describes the synthesis of a new bis-bifunctional derivative of 8-hydroxy-quinoline, its reaction with a number of divalent, first-row transition metals to form coordination polymers, and a thermogravimetric study of the thermal stability of the polymers. The ligand, 5,5'-[methylenebis(p-phenylenenitrilomethylidyne)]di-8-quinolinol was prepared in a condensation reaction between 5-formyl-8-hydroxyquinoline and 4,4'-methylenedianiline and subsequently treated with the acetate salts of Mn(II), Co(II), Ni(II), Cu(II), and Zn(II). The metal coordinated in the backbone of the polymer is shown to be an important factor in governing the thermal stability when the samples are heated in vacuum.
