Supramolecular formation of fibrous nanostructure in donor-acceptor dyad film

A novel oligothiophene and its fullerene derivative were synthesized and their film morphologies were investigated. AFM images revealed that the oligothiophene formed well-aligned fiber-like nanostructures in the film after being thermally annealed at its liquid-crystalline temperature. In the oligothiophene-fullerene dyad film, fibers were already formed in the as-cast film. Thermal annealing further enhanced the structural order and a long, partially aligned fibrous nanostructure with a width of around 10 nm and a length of as long as 200 nm was observed. Combined with the results of X-ray analysis, these features were ascribed to supramolecular self-assembly via π-π interaction of the oligothiophene groups. Photovoltaic properties of the molecules were also investigated. The Royal Society of Chemistry.

A series of novel, well-defined, unsymmetrical poly(ethylene glycol) chains of the type X(OCH2-CH2)nY (where X = protecting group; Y = nucleofuge or a different protecting group; n = 3, 6, 9, 12, 15, 18, and 24) were prepared in high yields by applying orthogonal protecting groups. The purity of the compounds was fully verified by elemental and high-resolution mass spectrometry analyses.
