PREPARATION OF 1,4-BIS(3-ETHYNYLTHIENO3,2-bTHIOPHEN-2- YL)BENZENE DERIVATIVES AS PEPTIDE-INSPIRED MOLECULES

摘要

1,4-Bis(3-ethynylthieno3,2-bthiophen-2-yl)benzene derivatives, as well as 1 -(3-ethynylthieno3,2-bthiophen-2-yl)-4-(2-ethynyl-3-thienyl)benzene derivative and 2,5-bis(2-ethynyl-3-thienyl)thieno3,2-bthiophene derivative, containing thieno3,2-bthiophene moieties with pseudoaxis, was prepared and their UV-vis spectra were studied. Extension of π-system through the central aromatic ring was suggested by the UV-vis spectra.
