Abstract
We present a theoretical investigation of the modifications that succe ssive oxidation induces on the geometric and electronic structures of the pi-electron donor dithiapyranylidene. The lengthening of the doubl e bonds and the shortening of the single bonds calculated as the molec ular charge increases indicate a gain of aromaticity with oxidation. B oth the geometric and the electronic structure of dithiapyranylidene s how a clear evolution towards those of biphenyl as oxidation takes pla ce.
