  Novel 9,10-Bis(1,3-dithiol-2-ylidene)-9,10- dihydroanthracene Derivatives Bridged by a Crown Ether Unit at the 1,8-Positions: A New Type of Redox-switchable Hosts Undergoing Reversible Structural Changes

  摘要：

  Novel redox-switchable host molecules (2) composed of a 9,10-bis(1,3-dithiol-2-ylidene)-9,10-dihydroanthracene unit and a crown ether moiety bridging the 1,8-positions have been synthesized. Cyclic voltammetry and X-Ray analyses revealed that the molecules undergo a significant structural change upon oxidation. 'H-NMR titration experiments on the neutral and dication states show that the binding abilities of the dication states for alkali metal cations (Li+, Na+, K+) are considerably lower than those of the neutral molecules. The binding properties of 2 were also investigated by cyclic voltammetry.
