A new heterocyclic base- 2-methylfuro[2,3-g]benzothiazole — and cyanine dyes with residues of this base were synthesized. It is shown that introduction of a furo[2,3] group in the 6,7 positions of the benzothiazole residue in the cyanines leads to a smaller bathochromic effect than the introduction of a thieno[2,3] and, particularly, a benzo group in the same positions.
