Gallazzi, Maria C.; Toscano, Francesca; Paganuzzi, Daniela; Bertarelli, Chiara; Farina, Alessandra; Zotti, Gianni published an article in Macromolecular Chemistry and Physics. The title of the article was 《Polythiophenes with unusual electrical and optical properties based on donor acceptor alternance strategy》.Computed Properties of C7H8O2S The author mentioned the following in the article:

The strategy of donor-acceptor alternation was adopted to reduce the energy gap in substituted polythiophenes; energy gaps down to 1.2 eV were obtained, which is a very low value in the class of polythiophenes. Alkoxy groups and dicyanoethenyl groups were used to prepare electron-rich and electron-poor thiophene units. The copolymers were obtained by coupling reaction methods (Suzuki) and by oxidative chem. and electrochem. polymerization of an opportunely designed substituted terthiophene. X-ray studies and spectroscopic data on the copolymers evidenced that the dicyanoethenyl group as substituent was rather steric demanding and susceptible of side reactions also preventing the n-doping of the material. The conductivity behavior was unusual but compatible with localized charge carriers. The experimental part of the paper was very detailed, including the reaction process of 2-(Thiophen-3-yl)-1,3-dioxolane(cas: 13250-82-3Computed Properties of C7H8O2S)

2-(Thiophen-3-yl)-1,3-dioxolane(cas: 13250-82-3) is one of dioxolane. 1,3-Dioxolane derivatives are recognized as important motifs for the construction of numerous pharmacologically active molecules as antiviral, antifungal, anti-HIV, and adrenoreceptor antagonists.Computed Properties of C7H8O2S

Protected acylthiophenes I (R = H, Me) were lithiated (BuLi) and then treated with Te and MeI and BuBr to give tellurides II (R1 = Me, Bu). Also prepared were isomeric III (R = H, Me; R1 = Me, Bu). The results came from multiple reactions, including the reaction of 2-(Thiophen-3-yl)-1,3-dioxolane(cas: 13250-82-3Product Details of 13250-82-3)

3-(Methoxymethoxymethyl)-2-thiophenesulfonamides and 3-hydroxymethyl-N-methoxymethyl-2-thiophenesulfonamides were shown to undergo cyclization when treated under anhydrous acidic conditions to provide a novel 2,3-dihydro-5H-thieno[2,3-e]-4,1,2-oxathiazepine ring system. Incorporation of a primary sulfonamide group into position seven of the mol. provided compounds which inhibit human carbonic anhydrase II.

Safety of 2-(Thiophen-3-yl)-1,3-dioxolaneOn September 30, 2008 ,《The effects of pendant vs. fused thiophene attachment upon the luminescence lifetimes and electrochemistry of tris(2,2′-bipyridine)ruthenium(II) complexes》 was published in European Journal of Inorganic Chemistry. The article was written by Nurkkala, Lasse J.; Steen, Robert O.; Friberg, Henrik K. J.; Haeggstroem, Johanna A.; Bernhardt, Paul V.; Riley, Mark J.; Dunne, Simon J.. The article contains the following contents:

The electrochem. and photophys. properties for a range of tris(2,2′-bipyridine)ruthenium(II) complexes in which a thiophene substituent is attached to one of the bipyridine ligands by either a pendant or a fused mode were determined The fused mode of attachment eliminates torsional movement between the thiophene unit and the chelating bipyridine, thereby offering optimal overlap between the π-systems of the chelating unit and the attached thiophene unit. The electrochem. properties of these complexes are similar; however, the luminescence lifetimes and intensities (in CH3CN at room temperature) are correlated to the mode of attachment. The longest luminescence lifetime was observed for [Ru(bpy)2{4-(thiophen-2-yl)-2,2′-bipyridine}]2+ (3000 ns), as compared to the prototypic [Ru(bpy)3]2+ (1745 ns). This complex also had the highest quantum yield (0.045). In the four isomeric complexes, where the thiophene ring was fused to the b or c face of the pyridine ring, the lifetimes fell in the interval 275-1510 ns, and the quantum yield ranged between 0.0047 and 0.014. In addition to this study using 2-(Thiophen-3-yl)-1,3-dioxolane, there are many other studies that have used 2-(Thiophen-3-yl)-1,3-dioxolane(cas: 13250-82-3Safety of 2-(Thiophen-3-yl)-1,3-dioxolane) was used in this study.
