A novel water soluble styrylquinolinium boronic acid has been synthesized in good yield. A selective oxidation of the C–B bond of the dye by hypochlorite was observed. During the oxidation of the dye, the replacement of the strong electron-withdrawing group (–BOH 2 ) by the electron-donating group (–OH) on the fluorophore resulted in a large red shift of the absorption and emission spectra...
Mechanochromism is found for a novel Boron-fluorine derivative bearing dimethylamino moieties (BOPIM-dma). The title compound shows weak or no fluorescence in organic solvents due to twisted intramolecular charge transfer (TICT), which induces energy lost via non-irradiation decay. However, intense fluorescence was observed in crystalline solid, obtained by recrystallization from organic solvents...
