Langmuir-blodgett multilayers of polymer-merocyanine-dye mixtures
Thin Solid Films, 1987Deposition studies of mixed monolayers of poly(methylmethacrylate) (PMMA) and merocyanine chromophore (M22) were carried out by the Langmuir-Blodgett technique. The equilibrium surface pressure vs. specific area of the monolayers at the air-water interface was measured for several mixtures. The specific area vs.

Dye aggregates formed in Langmuir–Blodgett films of amphiphilic merocyanine dyes
Current Applied Physics, 2006Abstract The electronic absorption spectra of pure Langmuir (L) films of 6MeDS prepared upon MgCl2, CaCl2, CdCl2, and CuCl2 aqueous solutions have shown that the Mg2+, Ca2+, and Cd2+ cations promote the J-aggregation of the dye, but the Cu2+ cation inhibits it.

Photoelectrochemical Studies of Electrodes Coated with Merocyanine Dye
Berichte der Bunsengesellschaft für physikalische Chemie, 1982AbstractDeposited films of merocyanine dye (3‐carboxymethyl‐5‐[2‐(3‐octadecyl‐2‐benzothiazolinylidene)ethylidene]‐2‐thioxo‐4‐thiazolidinone) show various kinds of intra‐ and intermolecular changes when they are heated and/or soaked in a neutral aqueous solution.

Octupolar Merocyanine Dyes: A New Class of Nonlinear Optical Chromophores
Chemistry – A European Journal, 2012AbstractA set of new octupolar merocyanine chromophores was designed and synthesized. These compounds were prepared from the reaction of 1,3,5‐triformyl‐2,4,6‐trihydroxybenzene with heterocyclic nucleophiles. Octupolar dyes were formed exclusively in their open‐dye form.

(Photo)isomerization dynamics of merocyanine dyes in solution
Journal of Photochemistry and Photobiology A: Chemistry, 1992Abstract The dynamics for isomerization of the first excited singlet state and of an unstable ground state conformer have been measured for a merocyanine dye in a variety of solvents. It is shown that the rates of both isomerizations depend on the temperature, viscosity and polarity of the surrounding medium.

Solvatochromism of a typical merocyanine dye. Further investigations
Journal of the Chemical Society, Faraday Transactions, 1993This paper reports on the solvatochromism of a new typical merocyanine dye of stilbazolium betaine. Solvatochromic absorption and fluorescence energy shifts of 2-(4-hydroxystyryl)-1-methylpyridinium betaine {4-[2-(1-methyl-2-pyridinio)vinyl]phenolate}, M, in 10 polar solvents are 15.0 and 6.0 kcal mol–1(1 cal = 4.184), respectively.Absorption and ...
