    Notes: A series of new macrobicyclic tetrathiafulvalenophanes of type 1 and 2 with three tetrathiafulvalene bridges has been prepared under high-dilution conditions using a stepwise selective protection-deprotection of tetrathiafulvalenethiolates. All the macrobicyclic tetrathiafulvalenes, along with the intermediate compounds 5 and 6 and the unexpected tetrathiafulvalene pentamers 17, were studied by cyclic voltammetry. An electrochemical investigation using the Bard-Anson equation and thin-layer cyclic voltammetry has been carried out, allowing an estimate of the number of electrons involved in each redox process of these multi-redox compounds. The X-ray crystal structure showing the unusual crystal packing of 2a is also presented.

    Notes: The synthesis of three novel macrocycles 3-5based on the two electron donors bis(2,5-dimethylpyrrolo)[3,4-d]tetrathiafulvalene (1) and 1,4-hydroquinone is presented. Their abilities to include the electron acceptor paraquat (6) have been investigated by UV/Vis and 1H NMR spectroscopy and an X-ray crystallographic analysis. Also, the complex formation between the cyclic acceptor cyclobis(paraquat-p-phenylene) (7) and different tetrathiafulvalene derivatives has been studied. A strong association between 1 and 7 facilitates the self-assembly of catenanes from the macrocycles 3-5. However, the preferred position of the cyclic acceptor 7in the catenanes around either the pyrrolo-annelated TTF or around the hydroquinone donor relies on a fine balance between all the individual noncovalent forces acting in cooperation.
