Solvent-dependent fluorescence lifetimes of estrone, 17β-estradiol and 17α-ethinylestradiol.


The fluorescence lifetimes of the estrogens, estrone, 17β-estradiol and 17α-ethinylestradiol, were studied in various solvents. The fluorescence lifetimes of 17β-estradiol and 17α-ethinylestradiol decreased from 4.7 to 0.9 ns as the solvent hydrogen bond accepting ability increased, in good agreement with other phenolic molecules. Estrone's two fluorescence… (More)
