Conjugated Chromophore Arrays with Unusually Large Hole Polaron Delocalization Lengths

by Kimihiro Susumu et al. Journal of the American Chemical Society, 9 Jun 2006 The future of high-speed electronics might very well be defined by linking together small, "electrically jumpy" molecules called chromophores. According to researchers at the University of Pennsylvania and St. Joseph's University, electrical charges can zip along chains of linked chromophores faster than any electrical charge yet observed in organic semiconductors, beating the previous benchmark in this regard by a factor of three. Their findings suggest the use of chromophore-based circuitry that could create nano-sized electronic components for numerous applications. Read more
