ABSTRACTNovel difunctional barbituric acid methine dyes have been synthesized for nonlinear optical applications. These Molecules have been reacted with Multi-functional isocyanates resulting in cross-linked polyurethanes. The thermal stability of the dye in crystalline form as well as dissolved in poly (Methylmethacrylate) was studied. Results suggest that although the dye crystals were thermally stable to 300 °C, when dissolved in a polymer the stability was markedly lower.

AbstractNickel dithiolene complexes, known for their strong NIR absorptions, high thermal stability, and lightfastness, are being considered for nonlinear-optical applications. In particular, phenylsubstituted nickel dithiolenes may be of interest because it has recently been shown that the hyperpolarizability of a phenyl-substituted 1,3-dithiole can be strongly dependent on the torsional angle of the phenyl group relative to the dithiole ring [1]. We report results from Hartree-Fock ab initio calculations of the second hyperpolarizability as a function of phenyl torsion.
