Abstract

Two-station [2] rotaxanes in the shape of a degenerate naphthalene (NP) shuttle and a nondegenerate monopyrrolotetrathiafulvalene (MPTTF)/NP redox-controllable switch have been synthesized and characterized in solution. Their dumbbell-shaped components are composed of polyether chains interrupted along their lengths by (i) two π-electron-rich stations two NP moieties or a MPTTF unit and a NP moiety with (ii) a rigid arylethynyl or ...
