PREPARATION OF 1,4-BIS(3-ETHYNYLTHIENO[3,2-b]THIOPHEN-2-YL)BENZENE DERIVATIVES AS PEPTIDE-INSPIRED MOLECULES

[摘要]：1,4-Bis(3-ethynylthieno[3,2-b]thiophen-2-yl)benzene derivatives, as well as 1-(3-ethynylthieno[3,2-b]thiophen-2-yl)-4-(2-ethynyl-3-thienyl)benzene derivative and 2,5-bis(2-ethynyl-3-thienyl)thieno[3,2-b]thiophene derivative, containing thieno[3,2-b]thiophene moieties with pseudoaxis, was prepared and their UV-vis spectra were studied. Extension of pi-system through the central aromatic ring was suggested by the UV-vis spectra.
