  Supramolecular assemblies and charge-transfer complexes of new nucleobase-functionalized tetrathiafulvalene (TTF) derivatives were investigated. Stille-type cross-coupling reaction between tributylstannylated TTF and iodinated nucleobase derivatives yielded mono- and bisnucleobase-substituted TTF derivatives. The electrochemical measurements revealed that the uracil- and cytosine-substituted derivatives possessed strong electron-donating abilities comparable to that of pristine TTF, and the electron-deficient features of adenine and guanine caused high potential shifts of the oxidation waves. In the solution-state electronic spectra, the intramolecular charge-transfer absorption bands were observed at a low-energy region. In the crystal structures, the donor molecules constructed supramolecular polymers by the complementary hydrogen-bonds inherent in nucleobases; a one-dimensional zigzag chain in the adenine-substituted derivative and a linear chain in the bis(uracil)-substituted derivative. The tetracyanoquinodimethane complexes of uracil- and cytosine-substituted derivatives possessed a mixed valence state exhibiting high conductivities (room-temperature conductivities = 10−2–10−1 S cm−1). In the cyananilic acid complexes, cytosine- and adenine-substituted TTF acted as electron-donors and proton-acceptors to yield simultaneous charge- and proton-transfer complexes.

  [GRAPHICS]A novel TTF-based donor with a uracil moiety, TTF-(1-n-butyluracil-5-yl) (TnbU), was synthesized. Crystal structures of both TnbU and the charge-transfer complex of TnbU-hydrogen cyananilate possess complementary double hydrogen bonds through uracil moieties and pi-stacking dimer structures between TTF skeletons. Furthermore, the TnbU-TCNQ charge-transfer complex shows a high electrical conductivity underlying the partial charge-transfer accompanied by a hydrogen-bonding interaction, which was substantiated in terms of the measurements of the IR, electronic spectra, and conductivity.

  Synthesis, crystal structures and redox properties Of 1,6-dithiapyrene (DTPY)-type electron donors functionalized with nucleobases (uracil, cytosine and adenine) were investigated. The electrochemical measurements showed that the uracil-substituted derivatives were slightly stronger electron-donors than DTPY, and the cytosine- and adenine-substitution caused a slight weakening of the electron-donating ability. In the crystal structures, DTPY-nucleobases constructed multidimensional assemblies by complementary hydrogen-bonds on the nucleobase moieties and pi-stacks and S center dot center dot center dot S interactions on the DTPY skeleton. The uracil derivative formed two kinds of hydrogen-bonded pairs with different H-bonding modes (Watson-Crick and reverse Watson-Crick types), both of which were further linked through pi-stacks on the DTPY skeleton to construct one-dimensional alternating columns. In the CH2Cl2 solvated crystal, the uracil derivative built up a two-dimensional pi-layer by the complementary hydrogen bonds and pi-stacks In the cytosine derivative, the complementary hydrogen bonded pair assembled by the pi-stacks and S center dot center dot center dot S interactions of the DTPY skeleton constructed a two-dimensional network The adenine derivative formed a channel structure by the one-dimensional pi-stack of complementary hydrogen-bonded pairs, where crystalline water molecules with a ladder-like hydrogen-bonded chain were included. Charge-transfer complexes of DTPY-nucleobases with tetracyanoquinodimethane possessed a neutral ground state and exhibited semiconductive behaviors with room temperature conductivities of 10(-6) to 10(-7) S cm(-1).
