A new diketopyrrolopyrrole derivative 1 exhibits excellent hole mobilities of 0.7 cm(2) V(-1) s(-1) and a current on/off ratio of 10(6) under ambient conditions in bottom-gate, top-contact organic thin film transistors (OTFTs) fabricated by vacuum deposition.

A high-throughput virtual screening of 45 000 diketopyrrolopyrrole dyes is performed to map their optoelectronic property space and screen for suitable dye-sensitized proton reduction solar-cells.

A diketopyrrolopyrrole dye was found to exhibit a three-step polymorphic transition by heating with thermosalient effects.

Molecular dynamics simulations show how the aggregation of polymer chains containing diketopyrrolopyrrole is modulated by chemical structure conjugated backbone.

The primary role of substituted side chains in organic semiconductors is to increase their solubility in common organic solvents. In the recent past, many literature reports have suggested that the side chains play a critical role in molecular packing and strongly impact the charge transport properties of conjugated polymers. In this work, we have investigated the influence of side-chains on th...

A π-conjugated polyazine containing diketopyrrolopyrrole (DPP) moiety, PDBTAZ, is synthesized through a simple condensation polymerization. PDBTAZ is found to be a high-performance ambipolar semiconductor in organic thin film transistors (OTFTs), showing an electron mobility of up to 0.41 cm(2) V(-1) s(-1) and a hole mobility of up to 0.36 cm(2) V(-1) s(-1).

A new diketopyrrolopyrrole (DPP)-based π-conjugated copolymer containing terselenophene units has been successfully synthesized. Its hole mobility reaches around 5.0 cm(2) V(-1) s(-1) in thin film transistors made from thermally annealed films. This proves that a longer terselenophene unit induced excellent charge transport properties.

Research activities in the field of diketopyrrolopyrrole (DPP)-based polymers are reviewed. Synthetic pathways to monomers and polymers, and the characteristic properties of the polymers are described. Potential applications in the field of organic electronic materials such as light emitting diodes, organic solar cells and organic field effect transistors are discussed.

Chemical vapour deposition enables the polymerisation of N -unsubstituted diketopyrrolopyrrole derivative into polymer thin film combining H-bonding and conjugated covalent bonds, increasing conductivity lifetime electronically excited states.
