Chemical Structure
Description
Owing to sulfur-containing functionality, a polycyclic aromatic system, 4,4''-Dihexyl-2,2':5',2''-terthiophene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 416.71 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
