N2 - Abstract: A series of new styryl type thiacarbocyanine dyes containing iodine atoms in the donor and/or acceptor moiety have been synthesized, and their electronic absorption spectra in the regions of singlet–singlet (S0–S1) and singlet–triplet (S0–T1) transitions have been studied. Introduction of iodine atoms into the dye molecules leads to a red shift of the absorption maximum, regardless of the iodine position. The electronic absorption spectra of dyes containing two and more iodine atoms showed a weak shoulder in the range from λ 650 to 1000 nm, which corresponds to the singlet–triplet transition.
