Demystifying the solvatochromic reversal in Brooker’s merocyanine dye

Phys. Chem. Chem. Phys., 2011
Based on hybrid QM/MM simulation techniques, we rationalize the spectacular solvatochromic reversal behavior observed for a stilbazolium merocyanine (SM) called Brooker's merocyanine dye. This solvatochromic reversal is attributed to a change in the solute π-electron distribution from zwitterionic to neutral following the change in solvents from polar ...

Photochemical switching through protonation in merocyanines

Journal of Photochemistry and Photobiology A: Chemistry, 1999
Abstract The ground- and excited-state energies for the planar and various 90-degree twisted structures of the merocyanine Me2N–CHCH–CHCH–CHO and its protonated form + Me 2 N CH–CHCH–CHCH–OH have been calculated by the AM1 method involving complete geometry optimization.

Solvent effects on merocyanine spectra

Spectrochimica Acta, 1958
Abstract Solvent effects on the visible absorption spectra of three merocyanine dyes are described. The dyes comprise two (I and II) of exceedingly high polarity, and a third (III) less polar than I and II but still highly polar by ordinary standards.

Merocyanines: potential new anticancer agents.

Anticancer research, 1988
We report the synthesis of a series of merocyanines and the structure-effect relationship as cytotoxic agents for human adenocarcinoma cells in vitro. The cytotoxicity of these compounds in vitro makes them potential anticancer agents. One of these compounds was found active on human and mouse tumor models.
