摘要

Poised to understand the influence of O- and S-heteroatoms on the chemical reactivity of dicarboxylic acids toward Pb(II), leading to crystalline metal-organic hybrid materials with distinct lattice architecture, dimensionality, and spectroscopic properties, the synthesis and physicochemical properties of binary/ternary Pb(II)-(O,S)-dicarboxylic acid-(phenanthroline) systems was investigated in aqueous media. pH-specific hydrothermal reactions of Pb(II) with O- and S-dicarboxylic acid ligands and phenanthroline (phen) afforded the variable dimensionality metal-organic Pb(II) polymers [Pb_ 3(oda)_3]_n (1), [Pb(phen)(oda)]_n (2), [Pb(tda)]_n (3), and [Pb(phen)(tda)]_n (4). The choice of O- vs S-ligands in the aqueous systems of Pb(II) and phenanthroline is linked to the emergence of distinct lattice composition-dimensionality (2D-3D) changes at the binary and ternary level, bestowing spectroscopic fingerprint identity to Pb(II) coordination and luminescence activity.
