Jh. Wang et al., The syntheses of a soluble diacetylene and its polymer with push-pull azobenzene and pyrimidine ring attached, SYNTH METAL, 113(1-2), 2000, pp. 73-76
A new unsymmetrical polydiacetylene having a pyrimidine ring and an azobenz
ene chromophore directly bound to the two ends of a diacetylene moiety was
synthesized with good yield. The diacetylene monomer could easily dissolve
in common organic solvents, and be polymerized thermally or under light ill
umination. Micro and macroscopic third-order susceptibilities were estimate
d for the yielded polymer. (C) 2000 Elsevier Science S.A. All rights reserv
