Abstract

Abstract We report the synthesis of novel resorcin [4] arene-based cavitands featuring two extended bridges consisting of quinoxaline-fused TTF (tetrathiafulvalene) moieties. In the neutral form, these cavitands were expected to adopt the vase form, whereas, upon oxidation, the open kite geometry should be preferred due to Coulombic repulsion between the two TTF radical cations (Scheme 2). The key step in the preparation of these novel ...
