Synthesis, structures, and photophysical properties of two novel trinuclear Hg(II)complexes
Two novel trinuclear Hg(II) complexes, namely, [Hg3Cl6(L-1)(2)] (1) and [Hg3Cl6(L-2)(2)] (2), (L1 = trans-4-[(p-N,N-dimethylamino)styryl]-N-acetic-acidpyridinium, L2 = trans-4-[(p-N-2-hydroxyethyl-N-methylamino)styryl]-N-acetic-acid pyridinium) have been synthesized and characterized by IR spectroscopy, elemental analysis, and X-ray single-crystal diffraction. In both 1 and 2, the tri- and tetra-coordinated Hg(II) atoms are linked by the carboxyl groups, resulting in the formation of trinuclear structures. Their linear absorption, one-photon fluorescence, two-photon fluorescence, and two-photon pumped up-conversion lasing are investigated. Upon pumped by 1064nm laser beam, complexes 1 and 2 exhibit excellent two-photon lasing at approximate to 627nm.
