Tetrathiafulvalene-containing pseudorotaxanes formed between dibenzylammonium salts and crown ethers

The synthesis of two tetrathiafulvalene (TTF) derivatives, one carrying arm s incorporating four dibenzylammonium centers and the other encompassing tw o annulated crown ether rings - i.e., hydrogen bond donor and acceptor func tions, respectively, is described. In the presence of macrocyclic polyether s - e.g., DB24C8 and BPP34C10 - and dibenzylammonium hexafluorophosphate, t hese two TTF derivatives form pseudorotaxanes as evidenced by H-1 NMR spect roscopy, mass spectrometry, and differential pulse voltammetry.
