Non-exponential distance dependence of bridge-mediated electronic coupling
Artikel i vetenskaplig tidskrift, 2006

Donor chromophores attached to oligo-(phenyleneethynylene) molecular bridges of varying length have attenuation factors for electron tunneling β that vary systematically with the donor-bridge (DB) energy gap (see picture). Investigations show that for bridges with ethynylene and vinylene repeating subunits, the electronic coupling increases with increasing donor-acceptor (DA) distance. A simple model accounts for this unexpected observation. (Figure Presented). © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
