Thin single-crystal growth of diacetylene monomer between a substrate and a glass plate has been investigated from the molten state. Among five different substrates examined, polydiacetylene single crystal, having the characteristics of pseudo-homo epitaxy, attained the best performance of growth control to give thin single crystals with the size of over one mm2 as well as uniaxial orientation. The crystals were successfully converted into polymer thin single crystals, which were usefull enough for nonlinear optical device fabrication.
