A crystal of carboxyl acid and at least one compound selected from the group consisting of amine and ammonia are mixed in an absence of a liquid medium. The carboxyl acid is conjugated diene such as (Z,Z)-muconic acid, the conjugated diene including a carboxyl group. The at least one nitrogen-containing compound selected from the group consisting of amine and ammonia is primary amine represented by RCH

, where R is an aryl group, or is a normal alkyl group that contains five or more carbon atoms. Moreover, such amine that is a bivalent group and that is represented by —Ar—N═N—Ar′—, where Ar and Ar′ are independently aromatic hydrocarbon bivalent groups, is intercalated in a layered crystal of a polymer such as polymuconic acid, the layered crystal including a carboxyl group. In this way, a novel photoresponsive polymer is obtained.
Also obtained is a crystal of ammonium carboxylate including at least one kind of carboxyl acid and at least one kind of amine, at least one kind of compound selected from (i) the at least one kind of carboxyl acid and (ii) the at least one kind of amine being a diacetylene derivative. The crystal of ammonium carboxylate is subjected to light or heat, to obtain a built-up type diacetylene polymer.
将羧酸晶体和至少一种从胺和氨组成的化合物混合在无液介质的情况下。羧酸是共轭二烯,例如(Z,Z)-巨环酸,共轭二烯包括一个羧基。从胺和氨组成的至少一种含氮化合物是由RCH2NH2表示的一级胺,其中R是芳基,或者是含有五个或更多碳原子的正常烷基。此外,这样的胺是一个双价基团,由—Ar—N═N—Ar′—表示,其中Ar和Ar′是独立的芳香族碳氢双价基团,被插入在聚合物的分层晶体中,例如聚巨环酸,分层晶体包括一个羧基。通过这种方式,获得了一种新型的光响应聚合物。同时获得了一种羧酸铵晶体,包括至少一种羧酸和至少一种胺,从(i)至少一种羧酸和(ii)至少一种胺中选出的至少一种化合物是二乙炔衍生物。将羧酸铵晶体经过光或热处理,获得一个堆积型二乙炔聚合物。
