A possible future molecular electronics technology will require molecules which can mediate charge transfer efficiently and which can perform switching functions. We use a mixed-valence approach to exploring the extent of charge delocalization across individual chalcogenophene units. So far we have focused mostly on thiophene- and selenophene-oligomers,1 but furans and tellurophenes are also considered. In related studies we have explored the possibility of photoswitching the extent of charge delocalization in organic mixed valence compounds with photochromic dithienylethene bridges.2 The outcomes of our investigations will be presented in the greater context of organic mixed valence and photoswitchable molecules.3,4 (1) Reuter, L.
