Improvement of fluorescence characteristics of coumarins: Syntheses and fluorescence properties of 6-methoxycoumarin and benzocoumarin derivatives as novel …
To improve the fluorescence characteristics, especially emission wavelength, of coumarins, various 3-substituted-6-methoxycoumarin derivatives were synthesized, and then benzocoumarin derivatives were also synthesized in expectation of the shift to the longer wavelength region by the extension of the conjugated system. Their fluorescence properties were investigated spectrophotometrically in acetonitrile and evaluated from the viewpoint ...
