General description

Thiophene belongs to the class of polycyclic aromatic sulfur heterocycles, which are carcinogenic compounds found in crude oil. Thiopenes are widely used as building blocks in many agrochemicals, pharmaceuticals, and material science.

Application

Thiophene may be used as an analytical reference standard for the quantification of the analyte in diesel oil and crude oil using two-dimensional gas chromatography with sulfur chemiluminescence detection.

We have measured the single-molecule conductance of a family of oligothiophenes comprising 1-6 thiophene moieties terminated with methyl-sulfide linkers using the scanning tunneling microscope-based break-junction technique. We find an anomalous behavior: the peak of the conductance histogram distribution does not
