A series of 5-(pyren-1-yl)penta-2,4-diyn-1-yl N-phenylcarbamates and N-benzylcarbamates were synthesized. Phenyl groups in the N-phenyl and N-benzyl moieties were unsubstituted (H-0 and H-1, respectively) and 3,4,5-trialkoxy substituted (C m O-0 and C m O-1, respectively), in which the alkyl groups introduced were methyl (m = 1), octyl (m = 8), dodecyl (m = 12), and hexadecyl (m = 16) groups. Upon UV irradiation, a regular 1,4-addition polymerization to form polydiacetylene was confirmed for H-0, H-1, C 8 O-1, C 12 O-1, and C 16 O-1. For C 1 O-0 and C 1 O-1, the crystal structures were solved, and the reasons the regular polymerization did not occur were clarified. From the powder X-ray diffraction study, crystallinities of C m O-1 were found to be lower than those of C m O-0, although C m O-1 regularly polymerized. This indicates that the total crystallinity is not directly related to local ordering around one-dimensional arrays for the polymerization direction. Polymerized C m O-1 species were soluble in chloroform. Their processability enabled us to fabricate cast films of polydiacetylene as well as the monomer. The conductivities of C 12 O-1 and the polymer (PC 12 O-1) were evaluated in the pristine and iodine-doped states and in the charge-transfer-complexed states with 2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane. A conductivity of 1.2 × 10 −2 S m −1 for iodine-doped PC 12 O-1 was achieved. In this case, pyrene moieties seemed to play an important role in realizing the appropriate electron transfer from pyrene moieties to iodine molecules and effective π conjugation between the pyrene moieties and the PDA backbone promoting charge transport.

“…In contrast to the formation of colorless and nonconjugated polymers obtained by the polymerization of diene derivatives, diyne derivatives give colored and π-conjugated polymers. They are promising materials for third-order nonlinear optics based on the π-electron delocalized polymer backbone . If both diyne and diene groups are incorporated in one system, they are expected to be polymerized in a crystal.…”

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.

We have studied the external-field-induced orientation of fibriform polydiacetylene nanocrystals in dispersions that we fabricated through reprecipitation followed by orientational fixation. The polymer employed was poly[1,6-di(N-carbazolyl)-2,4-hexadiyne] (polyDCHD). An AC electric field and a magnetic field were both effective agents for controlling the orientation of the nanocrystals in the dispersions; in contrast, we observed no orientational effect when applying a DC electric field. The application of the AC electric and magnetic fields led to different anisotropic orientations of the same dispersed nanocrystals. The degree of orientation depended on the AC frequency and the strength of the AC electric or magnetic field.
