摘要：

The synthesis of two 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 H-1 NMR spectroscopy, mass spectrometry, and differential pulse voltammetry.
