Abstract:  A series of compounds has been prepared in order to investigate the effect of the tetrahydrofurfuryl group attached to the α-position of dimethinemerocyanines upon the shift of the absorption maxima corresponding to the weakly pronounced electron effect (σ+ = 0.4). It is showed that the electron effect studied is more pronounced than that of the substances having the tetralrydrofurfuryl group located in the meso-position oisym- and asym-thia- and -selenacarbocyanine dyes.
