| Abstract: | A long-wavelength emssion Benzoh] coumarin aldehyde-8-(diethylamino)-2-oxo-2H-benzoh] coumarin aldehyde (BCA) was design and synthesized. Its photophysical properties in different solvents were investigated by absorption and fluorescence spectroscopy. An obvious slovatochromism and a large variation in color were observed. With the increase of solvent polarity, its luminescence changed from blue-green to red and the fluorescence quantum yield decreased from 0.98 to 0.26. |
