Kautsky

H. Kautsky showed the significance of singlet O2 in organic reactions his views were discounted at the time but the great importance of singlet O2 was rediscovered in 1964 by (a) C. S. Foote and S. Wexler, and (b) E. J. Corey and W. C. Taylor.

The formation of singlet oxygen through the Kautsky mechanism [78] was observed not only when sensibilization was induced by adsorbed dye molecules but also in case when sensibilization was provided by deposited oxides of transition metals [92, 93]. This is very important for understanding numerous heterogeneous and photocatalytic processes. 

Using semiconductor sensors we examined several peculiarities of photoemission of C>2. It occurred that concentration of C>2 in gaseous phase exhibits a linear dependence on intensity of exciting light which is completely consistent with the Kautsky mechanism (see the experimental schematics). Moreover, these results indicate that in this case the readsorption processes (as well as local heating of sensibilizer) are not important.

The requirement of hydrogen peroxide or oxygen in diazaquinone chemiluminescence appears to be another argument against the hypothesis of Albrecht 128> or of Kautsky and coworkers 132> that the diazaquinone is simply hydrolyzed to yield aminophthalate and diimine which in turn reduces other diazaquinone molecules to luminol in an excited state so that it then emits.

Similar effects were observed by Stigter e< al. (185) with silica and aluminum chloride. The assumption of hydrolytic adsorption is supported by an observed increase of conductivity upon addition of silica to aluminum chloride solutions. Kautsky and Wesslau (240) observed hydrolytic adsorption of Th + ions. The reaction scheme given above is a simplification since, in reality, solutions of basic iron or aluminum salts contain polynuclear complexes. The size of the aggregates depends on pH and concentration. Chromatographic separation of various metal ions on silica gel columns was first described by Schwab and Jockers (241). The role of hydrolytic adsorption in column chromatography on silica gel was stressed by Umland and Kirchner (242). The use of this technique in analytical separations was investigated in detail by Kohlschiitter and collaborators (243-246). An application to thin-layer chromatography was described by Seiler (247).
