The choice of protecting group is of crucial importance in the success of many steps in organic synthesis and the manipulation of polyfunctional molecules, since they can prevent the formation of undesired side products and reactions. Photoremovable protecting groups exhibit numerous advantages, such as the relatively soft conditions required for their deprotection and orthogonality with respect to acid‐ or base‐sensitive groups. They have found application for the controlled release of a variety of molecules in the areas of materials science, the caging and release of biologically significant compounds and in synthetic organic chemistry.
