Abstract

A 4-(pyrrolidin-1-yl) phenyl electron donor and 10-cyanoanthracen-9-yl electron acceptor are attached via alkyne linkages to the bridgehead carbon atoms of bicyclo [2.2. 2] octane and all three benzo-annulated bicyclo [2.2. 2] octanes. The σ-system of bicyclo [2.2. 2] octane provides a scaffold having nearly constant bridge geometry on which to append multiple, weakly interacting benzo π-bridges, so that the effect of incrementally increasing ...
