Substituent effects on photoresponsive nitric oxide release by N -nitrosoaniline derivatives
Abstract
and NO release. In particular, the introduction of a dimethylamino group completely suppressed the photoreaction. Quantum chemical calculations revealed that the differences in photoreactivity originate from differences in the propensity for transition to the charge transfer (CT) excited state. Furthermore, when the energy of the CT excited state is low, deactivation to the ground state is likely to occur, which may prevent N-N bond cleavage. Our results identify suitable structures to promote efficient bond cleavage following PeT, which should be helpful for developing various photofunctional molecules.
