In this work, we have found that large conjugated pyridinium betaines, molecules composed
by a donor (D) and acceptor (A) pair connected through a long conjugated chain, exhibit an …

We report a semiempirical investigation of the first excited states and of the spectroscopic
properties of resveratrol, a phytoalexin with well-known antioxidative properties, and of …

In this work we have investigated the ground state and others eletronic properties of the
biosensor 3-methyl pyrrole-4-carboxilic acid (MPC) oligomers and related compounds. We …

Interest in conductive organic polymers has considerably increased since the discovery in
1977 of the doped molecule polyacetylene. Recently, polymers of dithienopyrrole (DP) …

Resveratrol, a natural product derived from grapes, is a phytoalexin with antioxidative
activity. In this work we present initial results of an ongoing study of the geometry of the …

Molecular electronics has recently attracted a lot of attention due to promising application in
nanoscale electronic devices. In this review we highlight recent results in this field, focusing …

Two low band-gap polymers (gap energy∼ 1eV) based on carbon-bridged dithienyl
monomers have been investigated by density functional theory (B3LYP/6-31G) and …
