Synthesis of fluorescent 2-(2´,2´´-bithienyl)-1,3-benzothiazoles
Eight new bithienyl benzothiazole derivatives 1 were synthesised by reacting various 5-formyl-5´-alkoxy- or 5-formyl-5´-amino-2,2´-bithiophenes 2 with ortho-aminobenzenethiol in good to excelent yields. Compounds 1a-h were completely characterised by spectroscopic methods. Absorption and fluorescenc...
