Methods for Preparing Metal Ion Photocages: Application to the Synthesis of CrownCast
摘要:
Three different synthetic strategies were utilized in the construction of a novel class of macrocyclic containing o-nitrobenzhydrol group II cation cages. The synthetic methodology presented herein is unparalleled in scope toward the preparation of caged complexes for various main group and transition block cations.

photoactive group act as cages for divalent metalions. The uncaging mechanism of these complexes involves a photoreaction that converts the nitrobenzhydrol, which is para to the aniline nitrogen atom, into the corresponding nitrosobenzophenone. Resonance delocalization of the aniline into the distal carbonyl group of the photoproduct attenuates the ability of the nitrogen atom to interact with the
