The main section of the project involved a study of the electrochemical behaviour of the 1-phenylazo-2-naphthol system, some of which were found to form diphenylamine type products whilst some were found to dimerize upon electrolysis.1-Phenylazo-2naphthols undergo azo-hydrazone tautomerism, a phenomenon which was investigated by a wide range of analytical techniques. Much spectroscopic data including C n.m.r. (liquid and solid phase) and 360 DUiz N n.m.r. spectra were recorded and interpreted. The dyeing of fibres, light fastness tests and computational studies were also performed on these coloured molecules. Other conjugated systems investigated by electrochemical and chemical oxidative techniques included phenothiazines, azo-triazoles, azo-benzenes and furfurylidenimines.
