General description

Camphorquinone (CQ) absorbs UV radiation in the region of 200-300nm due to the Π−Π* transition and visible light (400-500nm) due to the n, Π* transition of the α-dicarbonyl chromophore.

Application

CQ-amines are used as a photo initiators for free radical polymerization. CQ was used as an initiator in the preparation of silver nanoparticle/silica/ polymer nanocomposites. Photopolymerization kinetics of dimethacrylates were studied using the CQ/amine initiator system.
