Abstract

Hydroxy-tethered platinum(II) complexes were synthesized and used as diol monomers for polyurethane synthesis. Polyurethanes with moderate molecular weights were obtained by conventional polyaddition with a diisocyanate. The polyurethane containing the platinum(II) complex substituted with t-Bu groups was soluble in common organic solvents, including CHCl3 and tetrahydrofuran. Segmented polyurethanes containing platinum(II) complex moieties were also synthesized using polytetrahydrofuran and 1,4-butanediol. These polyurethanes showed good elastic properties. The nonsegmented polyurethane exhibited distinguishable photoluminescence changes upon grinding in the solid state, while the segmented polyurethanes did not.
