Merocyanine Dyes with Improved Photostability
Organic Letters, 2007Merocyanine 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, 2000Abstract 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.

Merocyanine organic solar cells
Journal of Applied Physics, 1978Recently, we reported on the development of a new thin-film organic solar cell with an AM1 sunlight efficiency of about 0.7% for large area devices (∼1 cm2). This relatively high-efficiency MIS-Schottky barrier-type cell was based on merocyanine type photosensitizing dyes.

Photocontraction of Liquid Spiropyran-Merocyanine Films
Science, 1984Amorphous films of a photochromic spiropyran containing a mesogenic group melt, when exposed to heat together with irradiation, to yield a red fluid. This fluid contains aggregates of merocyanine molecules and exhibits marked contraction under light illumination.

Merocyanine-paclitaxel conjugates for photothermal induced chemotherapy
Journal of Materials Chemistry B, 2021Merocyanine-paclitaxel conjugates could form stable nanoparticles, which indicate the enhanced chemotherapy upon irradiation because of the photothermal effect.

Dipolar interaction driven dimerization of a merocyanine (MC) dye has been exploited to achieve non-covalently crosslinked stable micelles in water and reverse micelles in toluene with emissive properties from a MC-pendant amphiphilic block copolymer.

Polym. Chem., 2014
A combined experimental and theoretical study on the synthesis and solution isomerization behavior of main chain copolymers with multiple spiropyran incorporation is presented. A series of alternating copolymers P(SP-alt-Cx) of spiropyran (SP) and flexible linkers (Cx, x = 6,8,10) is synthesized by Suzuki polycondensation (SPC).

Protein damage by photoproducts of merocyanine 540
Free Radical Biology and Medicine, 1992Exposure of certain photoactive dyes to light prior to their use in biological systems (preactivation) has been shown to result in formation of long-lived cytotoxic photoproducts. The cytotoxic species responsible for the biological activity of preactivated merocyanine 540 (pMC540) appears to be a hydroperoxide generated by oxidation of ground-state ...
