Chemical Structure
Description
Structurally, 851817-11-3 [Anthra[2,3-b:6,7-b']bisthiene-5,11-diyldi(ethyne-2,1-diyl)]bis(triethylsilane) DTXSID10731257 (C34H56S2Si2) contains sulfur-containing functionality, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 585.11 g/mol, it falls into the moderately-high-molecular-weight range. 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).
