TETRATHIAFULVALENOPHANES AND THEIR CATENANES

Monomacrocycles of the two electron donors tetrathiafulvalene (TTF) an d 1,5-dioxynaphthalene have been prepared, together with three symmetr ic TTF-containing bismacrocycles, two of which have been prepared by a two-step deprotection-cyclization approach. By utilizing the donor-ac ceptor interactions of these donors with the dipyridinium dication of 1,1'-[1,4-phenylene-bis (methylene)]bis-4,4'-bipyridinium bis(hexafluo rophosphate), [2]catenanes were synthesized. In the case of one of the bismacrocycles it was possible to isolate a minor amount of a bis [2] catenane. The catenanes were characterized by H-1 NMR spectroscopy, el ectrospray mass spectroscopy (ESMS) and their fragmentation in the gas phase was also analysed by collisional activation (ESMS/MS). Also, on e tetramacrocyclic compound, the first TTF-based ribbon compound, has been synthesized. This control shows complex electrochemical propertie s.
