Article abstract of DOI:10.1039/ft9959104099

Spectra, photochromism and thermochromism of a spiro and a spiro have been investigated in cationic (CTAB, hexadecyltrimethylammonium bromide) and non-ionic (TX-100) micellar solutions and in sodium bis-2-ethylhexylsulfosuccinate (AOT)/toluene/water inverted-micelles.The spectral shifts of the photomerocyanine colour band provided information on the location of the molecules in these systems.From photokinetic study of the colour-forming and colour-fading reactions, the quantum yield and bleaching constant were determined.The thermal equilibrium constant of the spiro was spectrophotometrically measured.Comparison of the results obtained in microheterogeneous systems with those determined in a homogeneous solution indicated that thermo- and photo-colourability increase in TX-100 and CTAB micelles and decrease in inverted micelles.
