New push–pull conjugated polymers based on furo[3,4-c]pyrrole-4,6-dione (FPD) and selenopheno[3,4-c]pyrrole-4,6-dione (SePD) have been synthesized compared with their thieno[3,4-c]pyrrole-4,6-dione (TPD) analogues to investigate the effects of heteroatom electrooptical properties. The copolymers were using either Stille cross-coupling or direct heteroarylation polymerization (DHAP), latter method giving high molecular weights. Hypsochromic shifts band gaps observed for FPD-based (sulfur...
A high molecular weight alternating naphthalene diimide–bithiophene copolymer (poly{[N,N′-bis(2-octyldodecyl)-naphthalene-1,4,5,8-bis(dicarboximide)-2,6-diyl]-alt-5,5′-(2,2′-bithiophene)} (PNDIOD-T2)) has been prepared by direct (hetero)arylation polymerization (DHAP). Its structure and properties were investigated in comparison with the Stille-prepared commercial analog, N2200. It was found that new DHAP-derived PNDIOD-T2 known N2200 have similar optical absorption spectra HOMO/LUMO energy...
Direct C–H bond arylation reactions between heteroarenes and aryl halides provide an atom-economical "green" alternative to standard cross-coupling (Stille, Suzuki, etc.). Unfortunately, this reaction is not selective more than one type of may react, which, during polymerization reactions, can lead cross-linked materials. This paper reports the preparation PDTSiTPD PDTGeTPD, which have exhibited high efficiencies in organic solar cells, using direct (hetero)arylation methodologies. In order...
This work provides a unified understanding on how polymer molecular weight influences the blend photophysics, morphology, charge transport, and photovoltaic properties of all-polymer solar cells.
While the power conversion efficiency (PCE) of organic photovoltaics (OPV) on small‐area lab cells has rapidly increased during last few years, performance module level and availability OPV modules market is still limited, primarily due to specific constraints imposed by industrial production process. This work deals with upscaling process latest‐generation from fully solution‐processed modules, which are compatible roll‐to‐roll (R2R) printing. transfer demonstrated step material selection...
Organic polymers are currently investigated as active electrode materials. Here, new TPD-based were prepared and studied anode materials for lithium-ion battery.

Electron transport is critical to the use of n-type semiconducting polymers in diverse electronic and optoelectronic devices. Herein, we combine measurements field-effect electron mobility bulk with thin-film microstructure characterization elucidate polymer chain length dependence polymers, exemplified by a naphthalene diimide-biselenophene copolymer, PNDIBS. Both measured space–charge limited current method PNDIBS other copolymers exhibit peak at degree polymerization (DPc) 45–60 repeat...
