Nature of acid-induced fluorescence of 17alpha-methyltestosterone.
The fluorescence of the 17alpha-methyltestosterone-trichloroacetic acid reaction product, 1,2,10,15,16,17-hexahydro-10,17,17-trimethylcyclopenta[alpha]phenanthren-3-one, in strong acid was investigated. Structural requirements for fluorescence were derived from absorption and fluorescence studies of related phenanthrenones and cinnamylidene compounds possessing a similar chromophore. All compounds showed fluorescence intensity that was structure and pH dependent. Fluorescence is attributed to both enol and protonated species.
