2,5-Dithiophen-2-yl-thieno[3,2-b]thiophene (DTTS) is an organic semiconductor that has potential applications in polymer solar cells. The polymerization of DTTS can be achieved through a number of methods including thermal evaporation or solution-based processing. This polymerization produces a low molecular weight material with an interchain distance of approximately 2.5 Å and a redox potential approximately 0.5 V more positive than that of the parent compound. The photovoltaic properties of DTTS have been studied by systematically varying the methyl ester substituent at the para position and determining the effect on the carrier transport, kinetic stability, and optical absorption spectra. These studies show that when this substituent is methylated, DTTS has increased photovoltaic efficiency due to a reduced electron transport rate between chains and improved charge transfer kinetics.

3-Oxo-2,3-dihydrobenzo[b]thiophene1,1-dioxide is an antifungal drug that has been shown to have a broad spectrum of activity against both bacteria and fungi. It inhibits the synthesis of cell wall components by binding to the enzyme enoyl reductase in the cytoplasmic membrane of fungi. This binding prevents the reduction of 3-oxohexanoyl coenzyme A and blocks fatty acid synthesis. The methylene group on this molecule is able to act as an electron acceptor, which increases its polarizability and therefore its dipole moment. This increased dipole moment enhances the antibacterial activity of 3-Oxo-2,3-dihydrobenzo[b]thiophene1,1-dioxide.
