摘要: [reaction: see text] Effects of metal cation recognition on photosensitized E-Z isomerization 1,2-dichloroethylene have been investigated with two types m,p- and o,o'-podand (oligo-oxyethylene unit) benzophenones 2 3. With increasing size, the %Z ratio at photostationary state was changed from 67 to 91% for but remained almost unchanged (86-88%) These results were interpreted in terms variation excited triplet energy, E(T), associated complexation these photosensitizers
