General description

2,5-Dihydro-3,6-di-2-thienyl-pyrrolo[3,4-c]pyrrole-1,4-dione is a diketopyrrolopyrrole (DPP) based copolymer and are used widely in thin-film transistors and solar cell devices. This aromatic polymer has electron withdrawing groups and hence is very useful for the synthesis of narrow band gap donor-acceptor polymers which are used as active semiconductors for organic electronics. They give rise to high power conversion efficiency (PCE) in Organic Photovoltaic (OPV) Cells.

Application

Used in the synthesis of donor-acceptor polymers which are used in polymer field-effect transistors and bulk heterojunction solar cells.

Features and Benefits

Diketopyrrolopyrrole is planar and can accept hydrogen bonds/other electrostatic interactions which results in copolymers that have pi-pi stacking.

The singlet fission (SF) process discovered in bis(thienyl)diketopyrrolopyrroles (TDPPs) can boost their potential for photovoltaics (PV). The crystal structures of TDPP analogs carrying n-hexyl, n-butyl, or 2-(adamant-1-yl)ethyl substituents are similar, but contain increasingly slipped stacked neighbor molecules. The observed SF

We report the synthesis and polymerization of a novel thieno[3,2-b]thiophene-diketopyrrolopyrrole-based monomer. Copolymerization with thiophene afforded a polymer with a maximum hole mobility of 1.95 cm(2) V(-1) s(-1), which is the highest mobility from a polymer-based OFET reported to date. Bulk-heterojunction
