Abstract Two different types of fluorescent materials containing benzothiazolyl moiety, 2- (benzothiazol-2-yl) phenol derivatives and 3-(benzothiazol-2-yl) coumarin derivatives, were synthesized synchronously using ethyl cyanoacetate, appropriate aromatic aldehyde and 2- aminothiophenol as the starting materials under the catalysis of benzoic acid by one-pot reaction. This method has the advantages of mild reaction conditions, easy processing ...
