Abstract

Providing critical reviews of recent advances in photochemistry, including computational and organic aspects, the latest volume in the Series reflects the current interests in this area. It includes a series of highlights on photorelease processes (via two-photon excitation and Norrish type II reactions), the design of light-activated tissue bonding, photoresponsive molecular devices targeting nucleic acids, ECL based biosensing techniques, photochemical bond activation at metal centres, photoredox catalysis via aromatic hydrocarbons, photoinduced multicomponent reactions and asymmetric catalysis via triplet-state. This is essential reading for anyone wanting to keep up to date with the literature on photochemistry and its applications.
