Synthesis and non-linear optical properties of monopyrrolotetrathiafulvalene derived donor-pi-acceptor dyads

Abstract

The synthesis of novel donor-pi-acceptor dyads based on a pyrrolo-annelated tetrathiafulvalene unit is described. The linear and non-linear optical properties of these chromophores have been investigated, together with their redox properties. For a dyad containing a p-nitrophenyl acceptor group, a significant third-order optical non-linearity is observed.
