Abstract
The triplet quenching of several sensitizers (thioxanthone (TX), 2-chlorothioxanthone (CTX), xanthone (X), benzophenone (BP), pyrene (PY), benzil (BZ), and phenothiazine (PT)) was investigated with lipophilic substituted onium salts (iodonium I(1) and sulfonium salts S(1)) in benzene, n-heptane, and mixtures of these. Moreover, the triplet quenching of these sensitizers was also studied in acetonitrile with onium salts I(2) and S(2) with a similar pattern of substitution to the lipophilic salts.
