The J-aggregates behavior by mixing system in LB films of merocyanine dyes

摘要

The characteristics for J-aggregates behavior bymixing method of dyes LB films has been investigated. Toinvestigate J-aggregates characteristics of dye molecules, mixingmethod of two types were used. The first was to deposit themonolayer obtained by the mixed solution onto solid substrate(case 1) and the second was to deposit the monolayer obtained byeach spreading of dye molecule at the air-water interface ontosolid substrate (case2). Furthermore, the deposition state of LBfilms have been discussed from characterization of the formationof mixed J-aggregates by optical absorption spectra.
