Polymethine dyes — Furo[3,2-e]indolenine derivatives

7,8,8′-Trimethylfuro[3,2-e]indolenine and polymethine dyes of various types that are derivatives of this base were synthesized. It is shown that incorporation of a furo[3,2] group in the 4 and 5 positions of the indolenine residue in the cyanines leads to a smaller bathochromic shift of the absorption maxima than does the introduction of thieno and benzo groups in the same position.
