Victors, Anders, Phasin's and Karls work on donor-acceptor substituted Norbornadienes has been accepted for publication in the upcoming emerging investigator issue of ChemComm
Reported in the paper is a study on five diaryl-substituted norbornadienes with unprecedented characteristics in regard to performance towards molecular solar thermal applications. The introduced aryl-groups induce a significant red-shift in the UV/Vis absorption spectrum of the norbornadienes, while keeping the molecular weight low. Device experiments with a solar-simulator set-up demonstrates the potential use of these compounds in MOST energy storage. An interesting feature of this class of donor-acceptor norbonadienes is that they retain good quantum yield and thermal stability of their quadricyclane isomers and at the same time posses red-shift of absorption (appr. 195 nm compared to unsubstituted norbornadiene). This makes donor-acceptor norbornadienes a very exciting class of compounds to be considered for molecular solar thermal applications.
