WebAt the 5,5′ positions of the central bi/dithiophene units, the molecules possess 1,4-phenylalkynyl groups that bear either electron-donating (NPh 2) or electron-withdrawing (SO 2 CF 3) groups. The optical properties were experimentally studied and modelled via quantum chemistry computations of key configurations and conformations. WebWith the exception of the sulfur-bridged DTT, all of the fused bithiophenes exhibit a red-shifted absorbance (ca. 310–356 nm) due to the rigid, fused-ring nature of the tricyclic building blocks, with corresponding extinction coefficients of ca. 12,000–26,000 M − 1 cm − 1. The only exception here is the SiDT analogues, which seem to ...
