Competition between Photoinduced Electron Transfer and Heterolytic Cleavage on Boron in B-Phenoxy Substituted BODIPY Photocages
The photochemical reactivity of B-phenoxy-substituted BODIPY derivatives was studied to evaluate their suitability as photocleavable protecting groups (photocages) for phenol release. The phenoxy unit was modified with strong (CHO), neutral (CH2OH), or very weak (CH2OAc) electron-withdrawing groups (EWG) at the para-...
