A fluorescent photochromic mol., which is composed of a photochromic diarylethene (DE) and a fluorescent perylenebisimide (PBI), was synthesized and its fluorescence photoswitching was studied. The fluorescence quantum yield of the open-ring isomer is constant irresp. of solvent polarity, while that of the closed-ring isomer decreases with an increase in the dielec. constant of solvents. Femtosecond time-resolved transient and fluorescence lifetime measurements revealed that the fluorescence quenching of the closed-ring isomer is attributed to the intramol. electron transfer from the PBI chromophore to the DE unit. In the experiment, the researchers used many compounds, for example, 2,9-Di(tridecan-7-yl)anthra[2,1,9-def:6,5,10-d’e’f’]diisoquinoline-1,3,8,10(2H,9H)-tetraone (cas: 110590-84-6Reference of 110590-84-6).
2,9-Di(tridecan-7-yl)anthra[2,1,9-def:6,5,10-d’e’f’]diisoquinoline-1,3,8,10(2H,9H)-tetraone (cas: 110590-84-6) belongs to isoquinoline derivatives. Quinoline is a mancude organic heterobicyclic parent, an azaarene, an ortho-fused heteroarene and a member of isoquinolines. It protonates to form salts upon treatment with strong acids, such as HCl. It forms adducts with Lewis acids, such as BF3.Reference of 110590-84-6
