(1987) 30 figures, 217 pages, DM168, ISBN 3-540-17,55-X This book provides an excellent source of information on chemiluminescence and aspects of bioluminescence. It is written by two international authorities who have made major contributions in this field. The book is divided into four main sections. Section A covers the physicochemical background to chemiluminescence, Section B surveys a range of chemiluminescent reactions (autoxidation, peroxides, dioextans, peroxy oxalates, luminol and related compounds, acridines, imine peroxides, electrogenerated), bioluminescent reactions are briefly considered in Section C, and in the final section applications, instrumentation and practical demonstrations are described.A recurrent theme is the uncertainty surrounding the mechanism of the majority of chemiluminescent reactions and the numerous opportunities for both basic and applied research in this fascinating area of scientific endeavour. The authors' coverage of chemi-

Die Chemilumineszenzfahigkeit substituierter Phthalsaure-hydrazide geht allge mein mit dem Elektronen-Donatoreffekt der Substituenten parallel. Abweichungen von dieser Regel treten auDer bei besonders oxydationsempfindlichen Substituenten bei sterischer Resonanzhinderung auf, z. B. bei 3-Dimethylaminophthalhydrazid. Das sterisch nicht behinderte 4-Diathylamino-phthalhydrazid iibertrifft das Luminol deutlich.
Photophysical properties of 9,10-di[(l-naphthyl)-methyl]-9,10-dihydro-9,10-phenanthrenediol (1), 9,10-di(l-naphthyl)phenanthrene (2), 9,10-di(2-naphthyl) phenanthrene (3), 10,10-di(1 -naphthyI)- 9,10-dihydro-9-phenanthrone (5 a) and 10,10-di(2-naphthyl)-9,10-dihydro-9-phenanthrone (5 b) have been studied. In contrast to l,4-di(l-naphthyl)butane compound 1 shows strong (intramolecular) excimer fluorescence in dilute solution at room temperature. As a result of intramolecular triplettriplet energy transfer the phosphorescence of 2, 3, 5 a and 5 b stems from the naphthalene moieties. The increase (compared to naphthalene) of the rate constant of the radiative deactivation of the lowest triplet state is probably due in the case of 2 and 3 to the non-planarity of the molecules, which is expected to increase spin-orbit coupling, while in compounds 5 a and 5 b intramolecular chargetransfer interaction between the carbonyl group and the naphthalene moieties may be responsible for this effect. Delayed fluorescence (from the phenanthrene moiety) of 2 has been observed in fluid solution at room temperature, and an excitation mechanism is proposed
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
