Abstract
Michael addition of thiols to an electron deficient alkene functional group in reagents (1)-(3) give rise to fluorescence quantum yield enha ncements. In the absence of the thiol, photoinduced electron transfer (PET) takes place from the fluorophore to the alkene moiety. Such elec tron transfer is suppressed after the thiol reaction.
