(a) General synthetic route for the preparation of triphenylene side-chain PTmT homopolymers with different lengths of the aliphatic spacer. (b) Schematic view of the lamello-columnar structure of PT10T consisting of alternating triple rows of triphenylene columns and polythiophene sub-layers, arranged in a rectangular p2gg lattice involving twelve columns and two sub-layers (white frame). (c) Topographic AFM image of PTmT nanostructured thin film on silanized silicon wafer and terrace step profile determined from topography. (d) Typical transfer characteristic of a top-contact bottom-gate OFET based on PTmT polymers (PT10T).
