Donor/acceptor substituted oligothiophenes: Synthesis, spectroscopic and electrochemical properties
Seven new donor/acceptor oligothiophenes 1-2 were synthesized by Stille coupling in moderate to good yields. Compounds 1-2 were completely characterized by HRMS, H-1 NMR spectroscopy and by IR and UV-VIS spectroscopy. In agreement with the UV-VIS data and also with the electrochemical study the new donor-acceptor systems synthesized could have applications in NLO.
