【Abstract】 A number of substituted 7-amino coumarins C311, C47, C102, C152, C481 have been synthesized. Their spectral and lasing behaviour has heen measured. The data obtained in our experiments show that substituted 7-amino coumarins have the advantages of high efficiency, broad tunable band, and high chemical stability. The effects of the substitution on the behaviour has aJso been discussed.更多还原
