Abstract

The tridentate 1,3-di(N-pyrazolyl) benzene L 1 was synthesized from dibromobenzene and pyrazole. When reacted with K2PtC14 and IrCl3 the asymmetric complexes (µ-Cl)2(PtL1 )2 and (µ-Cl)2[lr L12]2 were obtained. The tridentate l ,3- dimethyl-4,6-(di-N-pyrazolyl) benzene ligand L2 , was synthesized from di-bromo-mxylene and pyrazole. The ligand was reacted with K2PtC14 to give L2 PtCl. Further reaction with phenylacetylene led to the air sensitive acetylide complex L2 PtC=C(C6H5). L2 PtCl could also be reacted with AgOTf in acetonitrile to give [L2 PtN=CCH3] OTf. Reaction with other late transition metals led to the di-chloro bridged iridium dimer (µ-Cl)2[L 2IrCl]2 and the square planar palladium complex L2 PdCI. Oxidation potentials and the photophysical properties of the compounds were then studied. Fluorescence was found to be the result of a combination of interligand charge transfer and metal to ligand charge transfer.
