Abstract

Abstract A series of substituted 3-benzothiazolylcoumarins was prepared from condensation of 2-hydroxy-benzaldehyde and 2-cyanomethylbenzothiazole to investigate the effect of the nature and position of substituents on their absorption and fluorescent behavior. Compounds with a substituent containing a heteroatom which attached at the C6 position showed a split broad absorption band. Solutions of these compounds in various solvents ...
