    Growth of thin single crystals from the melt of a diacetylene monomer, 2, 4-hexadiynylene di-p-toluenesulphonate (pts), between a substrate and a glass plate, has been investigated. Among five kinds of substrate examined, pseudo-homoepitaxy on poly-PTs substrate attained the best performance of growth control to give thin single crystals of pts with a developed surface of over 1 mmJ as well as uniaxial orientation, whereas the other four substrates, e.g. KCI single crystals and rubbed polyimide films, resulted in the formation of microcrystallites without any regular orientation under the same crystal growth conditions. The pts crystals were successfully converted into the single-crystalline polymer, with a quality suitable for nonlinear optical device fabrication.
