Abstract

Silica gel has been converted to silylated derivatives which can be converted to sensitizers for singlet oxygen formation. The silica gel sensitizers.,[Psi]-rose bengals,'are versatile and useful in both polar and nonpolar media.[Psi]-Rose bengal has been studied as a source of singlet oxygen and its uses in reactions of sulfite ion, tryptophan, and 2, 3-diphenyldioxene are reported. Results are compared with unbound and polystyrene-based rose bengal ([PI ...
