Аннотация:This work is devoted to the synthesis of a previously unknown class of bichromophoric carbocyanines based on 2,6-lutidine and 2,4,6-collidine. The compounds obtained were characterized by electronic spectra of the absorption. The spectral range of absorption maxima of the carbocyanines 3-4 is 620-670 nm (620-630 nm for 3a-b, 660-670 nm for 4a-c).
The work was carried out with the financial support of the Grant of the President of the Russian Federation for the state support of the leading scientific schools of the Russian Federation NSh-10268.2016.3.
