| Abstract: | New π-conjugated oligomers (1-3) combined of thiophene rings, C C units, and phenylene rings were synthesized. The monomer (1) was synthesized by Sonogashira cross-coupling reaction. Lithiation and oxidation of the monomer led to the formation of dimer (2) and trimer (3). Optical and electrochemical properties of compounds 1-3 were studied. The oligomers with thioacetyl moieties were synthesized for self-assembly. |
