Synthesis of new photoresponsive polymers containing trifluoromethyl-substituted norbornadiene moieties
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.
