Synthesis and properties of a novel photochromic compound with modulated fluorescence in the solid state.
A new photochromic compound, 1,3-diphenyl-4-(3-bromobenzal)-5-hydroxypyrazole 4-phenylsemicarbazone (DP3BrBP-PSC), has been prepared. Its photochromic and thermobleaching behavior, crystal structure, and fluorescent property have been investigated in detail. The results show that the compound exhibits reversible enol-keto photoisomerization due to the intermolecular double-proton transfer, excellent photostability, high fatigue resistance, and remarkable fluorescence.
