H. Hiratsuka et al., PHOTOCHEMICAL FORMATION OF 9-SILAANTHRACENES IN RIGID GLASS, Journal of the Chemical Society, Chemical Communications, (2), 1995, pp. 215-216
UV photolysis of 9,10-dihydro-9-silaanthracenes in 3-methylpentane gla
ss at 77 K results in the formation of 9-silaanthracenes and diphenylm
ethyl-type radicals; by use of a triplet quencher, it was confirmed th
at these were produced via the lowest triplet state.
