The Mitsunobu reaction is shown to be a versatile method for the incorporat
ion of pyromellitic diimide (PMDI) acceptors into new macrocyclic structure
s containing tetrathiafulvalene (TTF) donors. In the case of macrocycle 5,
the more efficient bis-pyrroloTTF donor was used instead of TTF Macrocycle
1 revealed distinct charge-transfer interactions in the trans-configuration
, but not in the corresponding cis-form. Depending on the spatial geometry,
inter- and intramolecular interactions between the TTF-donor and the PMDI-
acceptor take place. X-ray crystal structures of macrocycles 1-cis, 1-trans
, 2 and 5 are reported.
