Dual-mode photoswitching of luminescence [PDF]
Journal of the Chemical Society, Chemical Communications, 1995 The fluorescence and chirality of photoswitchable inherently dissymmetric alkenes cis 1 and trans-2-nitro-7-dimethylamino-9-(2',3'-dihydro-1'H-naphtho[2,1-b]thiopyran-1'-ylidene)-9H-thioxanthene 2 are reversibly modulated by irradiation whereas photoresponsive effects and emission are regulated by reversible protonation.
