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 th...

Description
Summary: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.
