A versatile synthesis of novel oligothiophene-nucleoside conjugates based on Cu(I)-catalyzed alkyne-azide cycloaddition ("click-reaction") has been developed. Complementary thymidine- and adenosine-functionalized quaterthiophenes form recognition-driven superstructures via hydrogen bonding and other competing intermolecular forces. Self-aggregated fibers up to 30 microm in length were characterized with atomic force microscopy.
