Photolysis studies on 1-(9-anthryl)-hexan-2-one (ABK) in solution show
ed it to react primarily via the Norrish type I process to produce ant
hrylmethyl and butyl radicals with a quantum yield of about 0.01. 1-(1
-Naphthyl)pentan-1-one (NBK) photolyzed with a similar low quantum yie
ld via the type II process with the major product being acetonaphthone
. The use of 9-anthrylmethyl-9'-fluorenyl ketone (AFK) and jBK as phot
osensitizers in the polymerization of methyl methacrylate and styrene
gave polymers which appear to be efficiently end capped with anthrylme
thyl groups.
