Micro- and nanostructuring of oligo- and polythiophenes in two and three dimensions

Abstract Oligothiophenes bearing methacrylic functionalities were two-dimensional-structured by stamping techniques. The localised monomer was hardened by radical polymerisation in UV light. The structures in micrometre- and nanometre-scale were characterised electrochemically by SECM. An inverse polymer opal with extremely high inner surface and periodicity was obtained by localising the photosensitive oligothiophene within an opal template of SiO 2 beads. Cyclic voltammetry of the oligothiophenes in aprotic solvents was carried out to examine possible electrochemical conversions. A self-assembling technique for lateral and vertical structuring of polythiophenes with pendant sulfonate and …
