Hydrogen bonds are noncovalent interactions able to improve the electronic properties of self-assembled semiconductors. Nevertheless, it is necessary control parameters influencing formation hydrogen achieve hierarchical structures with enhanced properties. In this work, we explore two hydrogen-bonded thiophene-capped diketopyrrolopyrrole (DPP) derivatives containing amides different topology (...

Calix[4]pyrrole-based porous organic polymers (P1–P3) for removing micropollutants from water were prepared. A bowl-shaped α,α,α,α-tetraalkynyl calix[4]pyrrole and diketopyrrolopyrrole monomer crosslinked via Sonogashira coupling to produce a 3D network polymer, P1. P1 proved too hydrophobic use as an adsorbent was converted the corresponding neutral polymer P2 (containing carboxylic acid group...

Donor–acceptor (D-A) polymers are promising materials for organic electrochemical transistors (OECTs), as they minimize detrimental faradaic side-reactions during OECT operation, yet their steady-state performance still lags far behind all-donor counterparts. We report three D-A based on the diketopyrrolopyrrole unit that afford performances similar to those of polymers, hence representing a si...

A green method for the synthesis of high-performance diketopyrrolopyrrole pigments using diethyl succinate in the presence of mixture of ionic liquids is reported. Although, alkaline condition is needed in the succinate ester route for synthesis of the pigments, in the present study, the replacement possibility of conventional organic base by mixture of BMIMOH and BMIMBF4 ionic liquids was inve...
