Abstract

Supramolecular assembly of side chain-conjugated polythiophenes were brought about by a interplay of dipole–dipole interactions and hydrogen bonding. Copolymers of (E)-3,5-dimethyl-4-(2-(thiophene-3-yl)vinyl) isoxazole (DTVI) and (E)-2-(2-(thiophen-3-yl) vinyl)-1H-benzo[d] imidazole (TVB) were synthesized and their ability to form self assemblies in solution as well as in thin film were explored at device conditions over ITO substrates. The twisted hierarchical assembly of polyTVB was found to improve the charge carrier mobility and is explained by a possible mechanism in which, an innate hierarchical self assembly through J-aggregates is formed in thin film prepared under device conditions. The copolymers of DTVI and TVB were studied for change in morphology using AFM, and GIXRD.
