    Abstract

    In order to obtain large crystals of butadiynyl-substituted, i.e., diacetylene-substituted, polydiacetylenes, octatetrayne arylurethane derivatives of 6,8,10,12-octadecatetrayne-1,18-diyl bis(arylcarbamate) were synthesized as solid-state polymerizable monomers. Their comparatively large single crystals were obtained by recrystallization or slow evaporation. The polymer structure was studied by X-ray crystallographic analysis, and the structure of polydiacetylene with butadiynyl groups, proposed previously by 13C NMR spectroscopy, was confirmed. The third-order nonlinear optical susceptibilities of the polymer evaluated using the THG Maker fringe method were 10-12-10-11 esu.
