“…They can react with unsaturated compounds to produce the [2+2] cyclo‐adduct and nucleophiles like amine, alcohol, and acid to give an amide, ester, and anhydride analogue. For instance, the benzodioxinone moiety as a photolytic precursor of ketene has been incorporated into either polymer end‐ or side‐ groups to enable highly efficient postmodification reactions …”

“…These methods permit the spatial and temporal control of the click processes, which are not applicable for the other click reactions . A variety of photoinduced click reactions have been reported recently, photoinitiated thiol–ene/thiol–yne coupling, photoinduced CuAAC, photochemically generated nitrile imines, photoinduced ketene chemistry, “strain promoted” cycloaddition reaction of the photochemically generated cycloalkynes and azides, and photochemical uncaging of hydroquinone moieties . Owing to these prominent advantages of the photoinduced click reactions, this chemistry has been rapidly implemented in polymer synthesis and modification, biomaterial functionalization, and surface modification …”

“…Lastly, photochemically generated quinoketenes proved useful for generating polymer/silica composite materials. Because ketenes react efficiently with silanols, the end‐functional PS materials could be photochemically grafted onto silica particles to generate a covalent organic/inorganic interface in a user‐friendly fashion …”
