We will report the multi-step synthesis and characterization of multiple photochromes in the perimidinespirohexadienone family in which the naphthalene moiety of the parent compound has been replaced with a quinoline moiety. This substitution has been made in an attempt to make the ground state reduction potential of the long wavelength isomer (LW) more positive, while not substantially changing the reduction potential of the short wavelength isomer (SW), nor the excitation energy of either. If successful, this should allow LW to act as a photooxidant, while SW should not, effecting gating of sensitivity toward photoinduced charge transfer.
