摘要: The synthesis, electrochemistry, and photophysics of a series of square planar Pt (II) complexes are reported. The complexes have the general structure C∧ N Pt (O∧ O), where C∧ N is a monoanionic cyclometalating ligand (eg, 2-phenylpyridyl, 2-(2 '-thienyl) pyridyl, 2-(4, 6-difluorophenyl) pyridyl, etc.) and O∧ O is a β-diketonato ligand. Reaction of K2PtCl4 with a HC∧ N ligand precursor forms the chloride-bridged dimer, C∧ N Pt (μ-Cl) 2Pt C∧ N, which is cleaved with β-diketones such as acetyl acetone (acacH) and dipivaloylmethane …
