  Synthesis of New Photoresponsive Polymers Containing Trifluoromethyl-Substituted Norbornadiene Moieties

  摘要：

  Polymers containing trifluoromethyl. (CF3)-substituted donor-acceptor NBD moieties in the side chain or in the main chain were synthesized by substitution or addition of a CF3-NBD-carboxylic acid derivative or by polycondensation of a CF3-NBD-dicarboxylic acid derivative. The photoisomerization of the NBD moieties in these polymers proceeded very smoothly to give the corresponding QC moieties. Furthermore, the NBD moieties exhibited efficient fatigue resistance.
