Photosensitive intramolecular electron transfer compounds
-
, (2008/06/13)
A compound of the general formula: where A is a moiety which absorbs radiation and enters an excited state in which it accepts an electron; D- is a moiety which donates an electron to the excited state A and releases a free radical; and L+ is a cationic linking group which tethers electron acceptor moiety A to electron donor moiety D-. Cationic linking moiety L+ has the formula: where L' is a moiety which forms a stable radical with acceptor moiety A upon transfer of an electron from donor moiety D- to electron acceptor moiety A, and G is a moiety which forms a leaving group upon transfer of the electron from donor moiety D- to acceptor moiety A.

Photoreactions of p-(benzoyl)benzyl trisubstituted ammonium tetraorganylborate salts for the generation of tertiary amines in solution and rigid matrices are described. Structural modification of the complexes allows study of the influence of steric and electronic effects on the photogeneration of amines. Flash photolysis, cyclic voltammetry and product analysis indicate that single electron transfer from borate to excited benzophenone is followed by homolytic C-N bond cleavage. Photoliberation of the tertiary amine is controlled by the rate of the electron transfer reaction.
