Research has been conducted on the 3,4-alkylenedioxypyrrole and 3,4-(1,3-propylenedioxy)-pyrolle functionalized derivatives. The synthesis of these derivatives as especially electron-rich monomers yielding electroactive and stable conducting polymers has been carried out and discussed.

The structural conditions that are required for the phi-interactions between two electroactive components was analyzed by utilizing a tetrathiafulvalene (TTF)-derived donor that is covalently attached to viologen acceptors. Analysis of intramolecular charge transfer interactions of the TTF-derived donor indicated the influence of the linker between the TTF and the bipyridinium unit to the conformation of the products. Furthermore, the systems with stronger donors exhibited more significant positive changes.

The synthesis of the first bis(pyrrolo(3,4-d))tetrathiafulvalenes is described. The redox behavior of the pyrrolo tetrathiafulvalenes is very similar to that of TTF itself, unlike other types of aromatic annelated tetrathiafulvalenes (TTFs) which have reasonably higher oxidation potentials than TTF. According to the two-probe conductivities of the tetracyanoquinodimethane (TCNQ) complexes of the N-phenyl compound and the N-methyl compound, these yield higher values than TTF-TCNQ under similar conditions, thus indicating the potential of pyrrolotetrathiafulvalenes as a new series of organic metal building blocks.

The synthesis and characterization of monopyrrolo(3,4-d)-annelated tetrathiafulvalene derivatives are described. The compounds were prepared by phosphate-promoted cross-coupling and by other unsymmetrical coupling methods. Cyclic voltammetric analysis showed that all the compounds have excellent reversible redox properties and have low oxidation potentials. The compounds are being evaluated as donors for the synthesis of new conducting charge-transfer salts.

A series of compounds has been prepared in which a tetrathiafulvalene (TTF)-derived donor is covalently tethered or bridged to one or more bipyridinium (viologen) acceptors. The relative degree of charge transfer observed in this series is discussed as a function of structure. The greatest CT effect is seen in the cyclophanes 9a-c and 13.
