Lowest triplet state of a simple merocyanine dye

The Journal of Chemical Physics, 1974
The lowest triplet state of 3-ethyl-5-(1,3-dithiolanylidene)-rhodanine has been studied in solution and in single crystals at liquid helium temperatures. This state is tentatively assigned as a ππ* state. The origin in single crystals is composed of two lines separated by 0.6 cm−1. These lines have been interpreted as the allowed Au and Bu factor-group

Photo- and Electroluminescence of Merocyanine Dye M-440

Molecular Crystals and Liquid Crystals, 2005
Spectral, photoluminescent (PL), and electroluminescent (EL) properties of thin films of M-440 merocyanine dye have been studied. The technique of making EL structures based on this dye is developed. Uniform yellow emission of a thin film of M-440 dye is observed at the direct bias voltage that corresponds to the injection part of current–voltage (C–V)

NIR-Absorbing Merocyanine Dyes for BHJ Solar Cells

Chemistry of Materials, 2014
We have synthesized a series of new, polymethine chain extended merocyanine dyes 1–4 bearing varied acceptor units and an aminothiophene donor moiety. The optical and electronic properties of these new merocyanines have been studied in comparison with their corresponding lower homologues 5–8, which contain two methine groups less, by UV–vis and electro-

Characterization of evaporated thin films of merocyanine dyes

Journal of Applied Physics, 1990
Vacuum evaporation of a merocyanine dye, 3-ethyl-5 [2-(3-ethyl-2-benzothiazolidene) ethyldene]-2-thioxo-4-thiazolidione, onto different substrates such as bare and surface-oxidized silicon wafers and a quartz glass substrate is done. There is a difference in color between a film deposited on the bare silicon substrate and one on either a quartz glass ...

Benzothiazole merocyanine dyes as middle pH optical sensors

Dyes and Pigments, 2020
Abstract Substituted merocyanine dyes were obtained by Knoevenagel condensation between formylated arylbenzothiazole and quaternary 2-alkylbenzothiazoles. The condensations were performed in the presence of sodium methoxide and the products were obtained with excellent yields after simple purification.

Merocyanine-dye photovoltaic cell on a plastic film

Applied Physics Letters, 1981
A flexible photovoltaic cell was produced by depositing a merocyanine-dye layer on a transparent electro-conducting film, which is a polyester film coated with ITO (indium-tin oxide). Two kinds of the layered structures on the films were examined; i.e., Al/merocyanine/ITO and Ag/merocyanine/ZnO/ITO structures. It was found that the latter structure was
