We are investigating the synthesis of new luminescent square planar platinum(II) compounds. 9-hydroxyphenalenone (Hpal) was synthesized from 2-methoxynaphthalene and cinnamoyl chloride with a 42.6% percent yield. Hpal was reacted with a cyclometalated platinum(II) chloro-bridged dimer, [Pt(thpy)Cl]2 (where thpy = 2-thienylpyridine), to yield Pt(thpy)(pal). Pt(thpy)(pal) was crystallized to form dark red crystals. The characterization of these compounds by 1D and 2D-nuclear magnetic resonance spectroscopy and mass spectroscopy is reported. X-ray crystallography was performed on the Pt(thpy)(pal) crystals and a crystal structure was obtained.  Preliminary investigations of their luminescent properties will also be reported.
