Beschreibung:
<jats:p>The HOMO (H) of the Npe donor and the LUMO (L) of the acceptor (TCNB, TCNQ) resemble the H and L of the donor:acceptor complexes, respectively (Npe:TCNB, Npe:TCNQ). These orbital similarities correlate to a large degree of charge transfer in the H to L electronic transition.</jats:p>
