Abstract: NEW MATERIAL:A diacetylene compound of formula I (R is hydroxymethyl, 4-hydroxybutyl or their toluenesulfonic acid ester or phenyl-carbamic acid ester). EXAMPLE:1-(N-carbazoline)-5-hydroxy-1,3-pentadiyne. USE:Useful as a monomer for forming a polymeric semiconductor crystal or a polymer crystal exhibiting singular optical characteristics. Polydiacetylene crystal has excellent electrical and optical properties. The solid-phase polymerization of the monomer can be carried out by the heating, gamma-ray irradiation, etc., of a crystal sealed in a glass tube in vacuum or in an inert gas atmosphere. PREPARATION:The compound of formula I can be produced e.g. by asymmetric coupling of N-ethynylcarbazole of formula II with a 1-bromopropyn-3-ol of formula III (n is 1 or 4).
