Provided herein are photochromic organic compounds of Formula I or Formula II, which are useful as molecular switches capable of being triggered via a cis/trans isomerization process. Methods of using the molecular switch compounds to form photopharmaceutical compounds that may be used to provide selective spatiotemporal activation of pharmaceutical agents are also disclosed.

Here we report the synthesis and characterization of a BF(2)-azo complex that can be induced to isomerize without the need of deleterious UV light. The complexation of the azo group with BF(2), coupled with the extended conjugation of the N═N π-electrons, increases the energy of the n-π* transitions and introduces new π-nonbonding (π(nb)) to π* transitions that dominate the visible region. The well
