title: Self-complementary nucleoside-thiophene hybrid systems: synthesis and supramolecular organization.
abstract: Versatile synthetic methods towards a variety of thiophene-nucleobase hybrid systems are reported. Adenine- and thymine-based modified nucleosides characterized by a bithiophene unit linked to the C5' or C8 position through an ethylenamino or an ethylensulfanyl bridge were synthesized and successfully polymerized in the presence of FeCl(3) . The self-organization properties of the pure polymers as well as their mixtures - with complementary nucleobases - were investigated by means of optical microscopy and AFM in cast film showing complex supramolecular structures resulting from the interplay of multiple intermolecular interactions.
