| Abstract: | The synthesis, structures, and optical and electrochemical characteristics of novel crown-containing styryl mono-and polythiophenes
were described. The double bonds were constructed by the Horner-Wadsworth-Emmons method. The Suzuki and Stille cross-coupling
reactions were used to create polythiophene chains. Optical measurements revealed intense absorption and fluorescence of crown-containing
polythiophenes; the band positions and shapes in their absorption and emission spectra depend on the structure of the polythiophene.
The electrochemical characteristics of the compounds obtained were measured.
