Abstract

A series of 4,8-benzobisthiazole (BBT) containing copolymers with bisthienyl-diketopyrrolopyrrole (DPP), dithienopyrrole (DTP), benzothiadiazole (BT), benzodithiophene (BDT) or 4,4’-dialkoxybithiazole (BTz) comonomers were designed and synthesised. The resulting polymers possess a conjugation pathway that is orthogonal to the traditional 2,6-BBT unit, facilitating intramolecular non-covalent interaction between strategically placed heteroatoms of neighbouring monomer units. Such interactions enable a control over the degree of planarity through altering the number and strength of non-covalent interactions, in turn allowing for tuning of the band gap. Incorporation of the 4,8-BBT copolymers as donor material in organic photovoltaic (OPV) and p-type semiconductors in organic field effect transistor (OFET) devices gave performances up to 4.45% and 3.06 × 10-2 cm2 V-1 s-1 for pBT2ThBBT and pDPP2ThBBT respectively.
