Abstract: | The formation ofJ-aggregates of three polymethine dyes in solutions and in Langmuir-Blodgett (LB) polylayers was studied. The dyes formJ-aggregates in mixtures of solvents of different polarity: hexane-chloroform and heptane-chloroform taken in various ratios. The formation ofJ-aggregates in LB polylayers depends on the type of matrix and on the matrix: dye ratio.Translated fromIzvestiya Akademii Nauk.
