The formation of J-aggregates in the mutual mixing LB films of [6Me-DS] 1-x [DO] x , [DS] 1-x [DO] x have been studied by optical absorbance, fluorescence and surface pressure-area isotherms. Here, 6Me-DS, DS and DO show three types of surface active merocyanine dyes. Both sharp J-band absorbance and fluorescence, being observed in the [6Me-DS] film,...
Optical absorption and fluorescence, as well as electron spin resonance measurements were performed on Langmuir-Blodgett films of binary mixtures of three kinds of merocyanine dyes, i.e. DO, DS and DSe, where DS and DSe form J-like aggregates (but DO does not) in single-component films. The observed optical absorption spectra of mixed films were markedly dependent on the combination of dyes. [DS]...
