Monomers and aggregates of Merocyanine 540 (MC540) in water are able to photoisomerize. The shape of the photoisomer absorption spectrum is very similar to that of the ground state. Triplet state of MC540 in water has been produced by energy transfer from triplet anthracene and displays a broad absorption spectrum between 600 and 700 nm. The triplet state may also be produced by direct excitation of MC540 with UV light. However, when the dye is excited by visible light, no triplet state absorbance in the red could be detected so that the triplet yield of MC540 in water seems to be excitation wavelength dependent.

Les études des interactions entre la lumière et la matière relèvent du domaine de la physique mais elles ont des implications importantes en chimie et en biologie. Dans cet article, nous présenterons trois exemples, dans lesquels le phénomène de l'absorption lumineuse par certains chromophores et les réactions photochimiques, initiées à partir des différents états excités, constituent les étapes primaires de réactions photobiologiques qui peuvent avoir des conséquences aussi diverses que l'apparition de mutations dans les chromosomes et l'oxydation des constituants de membranes. Ces réactions biologiques sont appelées réactions de photosensibilisation et elles ont des implications importantes dans de nombreux domaines des sciences fondamentales et appliquées. [less ▲]

The quantum yields of singlet oxygen production by merocyanine 540 have been measured during visible light irradiation performed in methanol and ethanol. These appear to be one hundred times smaller than the quantum yield for rose bengal measured under the same conditions. Flash photolysis experiments demonstrate the ability of merocyanine 540 molecules to isomerize under visible light irradiation: the isomerization quantum yields are about 0.65 in both ethanol and methanol. This information combined with the fluorescence quantum yield data account for the low values for singlet oxygen production. [less ▲]
