tetrathiafulvalene (TTF) derivatives, one carrying arms incorporating four dibenzylammonium centers and the other encompassing two annulated crown ether rings—i.e., hydrogen bond donor and acceptor functions, respectively, is described. In the presence of macrocyclic polyethers—e.g., DB24C8 and BPP34C10—and dibenzylammonium hexafluorophosphate, these two TTF derivatives form pseudorotaxanes as evidenced by 1H NMR
