TTF-cytosine dyad as an electron-donor molecule having proton-accepting ability: Formation of hemiprotonated cytosine dimer in I-3(-) salt
A tetrathiafulvalene (TTF) derivative with a cytosine moiety was designed and synthesized as a bi-functional molecule with both electron-donating and proton-accepting abilities. In the crystal Of 13 salt, TTF-cytosine dyad formed a hemiprotonated dimer through triple hydrogen-bonds with radical cationic state of the TTF moieties.
