摘要

Abstract Efficient synthetic procedures for the preparation of b-trithiophenes (dithieno [2, 3-b: 3′, 2′-d] thiophene) and two macrocyclic compounds, tetra [2, 3-thienylene] and hexa [2, 3- thienylene] bearing trimethylsilyl (TMS) groups from 2, 2′-dibromo-5, 5′-bistrimethylsilanyl [3, 3′] bithiophenyl are reported. The UV-Vis spectra property and crystal structures of these macrocyclic oligothiophenes are described.
