Choi, Dong Hoon published the artcileEffect of photodimerization of chalcone moiety on the temporal stability of optically induced birefringence in photoresponsive polymers bearing a p-methoxyazobenzene, HPLC of Formula: 135529-02-1, the publication is Korea Polymer Journal (1999), 7(3), 189-195, database is CAplus.
We synthesized three methacrylate monomers containing chalcone moiety, mesogenic unit, and p-methoxyazobenzene chromophore, resp., and copolymers and homopolymers were prepared Trans-to-cis photoisomerization was observed under the exposure of UV. The kinetic study of trans-to-cis photoisomerization was performed in three different polymers. Reorientation of polar azobenzene mols. induced optical anisotropy under a linearly polarized light at 365 nm. The azobenzene unit underwent photoisomerization, and photodimerization was achieved in chalcone moieties under the same range light wavelength, while reorientation of azobenzene mol. was observed followed by photodimerization of chalcone moieties and the optically induced birefringence; the temporal stability was monitored without excitation light.
