Design and Photonics of Merocyanine Dyes

The Chemical Record, 2023
AbstractMerocyanines, thanks to their easily adjustable electronic structure, appear to be the most versatile and promising functional dyes. Their D–π–A framework offers ample opportunities for custom design through variations in both donor/acceptor end‐groups and the π‐conjugated polymethine chain, and leads to a broad range of practical properties ...

Merocyanine Dyes with Improved Photostability

Organic Letters, 2007
Merocyanine dyes have proven valuable for live cell fluorescence imaging applications, but many structures have been limited by rapid photobleaching. We show that photostability is substantially enhanced for merocyanines having a cyano group at a specific position in the central polymethine chain.

Merocyanine and Photomerocyanine Dyes

Molecular Crystals and Liquid Crystals Science and Technology. Section A. Molecular Crystals and Liquid Crystals, 2000
Abstract We give a review of results from work on merocyanines (MC) and photomerocyanines (PMC) reporting the most stable isomeric forms from X-ray structural and NMR spectral analysis. We also give new X-ray data, 1H-1H NOESY, 1H and 13C-NMR results for MC's.
