5-Phenyl-l,2,3,4-tetrahydronaphthalene derivatives: Synthesis, spectroscopic and electrochemical investigation

摘要

A series of novel dyes, whose structures are based on 5-phenyl-l,2,3,4-tetrahydronaphthalene skeleton have been fully synthesized and characterized. The dyes were prepared in two-stage synthesis reaction. The 2-cyano-3-[4-aminophenyl]-2-propenamide derivatives, and the final dyes were characterized by ~1H and ~(13)C NMR spectroscopy and their purity was checked by thin-layer chromatography and finally HPLC. The spectroscopic properties of the prepared dyes were studied in four different solvents.
