We present a comprehensive study of resonance formation in electron collisions with thiophene. Detailed calculations have been performed using the ab initio R-matrix method. Absolute differential cross sections for electron impact excitation up to 18 eV and for two scattering angles, 90 and 135°, have been measured. Agreement between the calculated and measured experimental cross sections is very good. Three shape resonances previously described, two of π* character and one σ*, as well as a number of resonances of core-excited or mixed character are identified and characterized in the calculations. The measured cross sections provide experimental confirmation for a number of the core-excited resonances. The link between these resonances and prior DEA experiments is discussed.

“…However, the reaction was improved neither by the use of the thioether 9 6 nor the sulfone 10. 5 In the latter case the regioselectivity of the deprotonation was lost, as illustrated by the formation of the tetrasilylated compound 11 upon treatment of the anion solution with Me 3 SiCl. The structure of 11 was confirmed by X-ray analysis.…”

Oligomers and soluble polymers incorporating conjugated α-oligothiophene units bridged by sulfide and sulfone groups are reported. The oligomers and polymers are characterized by solution 1 H NMR spectroscopy, differential scanning calorimetry, thermogravimetric analysis, cyclic voltammetry, gel permeation chromatography, and photophysical methods. The energies of the frontier orbitals, the physical properties, and the optical absorption and emission of these oligomers and polymers were found to be dependent on the oxidation state of the bridging sulfur.
