Description / Table of Contents:
This text examines organic, physical and materials photochemistry. It reports the first example of a TiO2 sensitization with a fullerene-based donor-acceptor dyad, and covers halophenols, diflusinal photochemistry, hydroxystyrenes, acetylenes, and other related compounds. The volume also investigates whether c,d-alkenes influence the efficiency and course of light-induced reactions, and more.
