Two thienopyrrolodione (TPD)-based polymers, 24DTT-TPD and 24DTS-TPD, were synthesized by carrying out Stille coupling reactions. The obtained polymers were characterized by 1H NMR, FT-IR, mass analysis, UV-visible spectroscopy, cyclic voltammetry, differential scanning calorimetry (DSC), and thermogravimetric analysis (TGA). The deposited films were characterized by X-ray diffraction. Synthesized polymers showed good solubility in common solvents. The solution-processed organic field-effect transistors showed field-effect mobility values of 4.5 × 10-5 cm2/Vs for 24DTT-TPD and 2.9 × 10-2 cm2/Vs for 24 DTS-TPD at optimal conditions.

Branched-alkyl-substituted poly(thieno[3,4-c]pyrrole-4,6-dione-alt-3,4-difluorothiophene) (PTPD[2F]T) can be used as a polymer acceptor in bulk heterojunction (BHJ) solar cells with a low-band-gap polymer donor (PCE10) commonly used with fullerenes. The “all-polymer” BHJ devices made with PTPD[2F]T achieve efficiencies of up to 4.4 %. While, to date, most efficient polymer acceptors are based on perylenediimide or naphthalenediimide motifs, our study of PTPD[2F]T polymers shows that linear, all-thiophene systems with adequately substituted main chains can also be conducive to efficient BHJ solar cells with polymer donors.

Two n-type molecular organic semiconductors (TI-BDF1 and TI-BDF2) consisting of thiophene-substituted indolin-2-one (TI) and benzodifurandione (BDF) with different branched side-chains have been synthesized to study the effect of molecular structure on molecular order, liquid crystal (LC) properties, and charge-transport. By tuning the branching point of the side-chains, TI-BDF2 shows a preferable edge-on π-face orientation and a high degree of liquid crystallinity, resulting in 4 orders of magnitude higher electron mobility than that of TI-BDF1. Subsequent n-doping of TI-BDF2 thin film with a thermally stable phosphonium salt affords a high electrical conductivity of 0.4 S cm-1.
