We have investigated that photoreactivities of a series of diynediammonium dienecarboxylates in the crystalline state. In the case of 4,4′- butadiynedibenzylammonium disorbate, almost all diene moieties were polymerized during photoirradiation for 8 h. On the other hand, the conversion of diyne moieties was still low. Crystal structure of the monomer crystal indicates that the alignment of diene moieties is very similar to those of topochemically polymerizable crystals of diene derivatives. Even though the translation distance of diyne moieties is also suitable for the polymerization, the tilt angle is different from the ideal angle. It is the reason why the conversion of diyne moieties was low. By X-ray single-crystal structure analysis of the polymer crystal, we confirmed that the polymerization proceeded via topochemical reaction mechanism indeed. On the other hand, photodimerization of diene moieties in the crystals of 2,4-hexadiyne-1,6-diammonium (E, E)-muconate occurred because of the face-to-face alignment of dienes at a distance of 3.8 Å.
