A Redox-Active Tetrathiafulvalene [2]Pseudorotaxane: Spectroelectrochemical and Cyclic Voltammetric Studies of the Highly-Reversible Complexation/Decomplexation Process
摘要:
The complexation of TTF 2 and cyclobis(paraquat-p-phenylene) 1(4+) has been studied by cyclic voltammetry and by spectroelectrochemistry: shifts in the redox potentials for the TTF and the 1(4+) components of 45 and 30 mV, respectively, occur upon complexation. Decomplexation of 2.1(4+). upon oxidation of the TTF unit to the cation radical species has been monitored by spectroelectrochemistry. The complexation/decomplexation process is highly reversible over at least 10 electrochemical cycles, and this process is accompanied by a color change of the solution from dark green (complexed) to pale brown (uncomplexed) which is clearly visible to the naked eye.

corresponding bis(hydroxymethyl) derivative (yellow) can act as guests for the π‐electron accepting cyclophane cyclobis(paraquat‐p‐phenylene) host (blue) and appear as promising building blocks for further development of electroactive molecular machines based on cyclobis(paraquat‐p‐phenylene).
