✦ Synopsis

Azobenzene dyes derived from various anilines and aminothiahetcrocycles azo-coupled with commercially important N,N-dicthyl-m-toluidine (T series) and N,N-diethyl-m-acetylaminoaniline (A series) are positively solvatochromic. The visible spectra of 16 pairs or derivatives have bccn measured in up to 22 solvents, and the transition energies related to Kamlet -Taft solvent polarity parameters. In general, A-series dyes are [*] Michael G. Hutchiiigs BASF plc. P. 0. Box 4. Hexagon Houqe, Blackley, Manchester M98ZB ( I J K
