Multicolored electrochromism from benzodipyrrolidone-based ambipolar electrochromes at a fixed potential

A series of ambipolar electrochromic (EC) materials composed of electron-withdrawing benzodipyrrolidone (BDP) moieties have been designed and synthesized. Upon incorporating different electron donors, various colors covering the whole visible range are ac

Semiconducting polymers

The invention relates to novel polymers containing repeating units based on benzodifuran, benzodipyrrole or benzodithiophene, monomers and methods for their preparation, their use as semiconductors in organic electronic (OE) devices, especially in organic

Reduced roughness for improved mobility in benzodipyrrolidone-based, n-type OFETS

A series of six phenyl-flanked benzodipyrrolidone-based copolymers are designed and synthesised: three exhibit backbone in-plane curvature or torsional twisting, while the other three remain planar and linear. While the former may appear less crystalline

Synthesis and optophysical properties of dimeric aza-BODIPY dyes with a push-pull benzodipyrrolidone core

A series of benzodipyrrolidone-based dimeric aza-BODIPY dyes with a push-pull structure are synthesized. Single crystal X-ray diffraction demonstrates these extended aza-BODIPY dyes are planar. The resulting aza-BODIPY chromophores exhibit intense absorpt

Synthesis and optophysical properties of dimeric aza-BODIPY dyes with a push-pull benzodipyrrolidone core

A series of benzodipyrrolidone-based dimeric aza-BODIPY dyes with a push-pull structure are synthesized. Single crystal X-ray diffraction demonstrates these extended aza-BODIPY dyes are planar. The resulting aza-BODIPY chromophores exhibit intense absorpt

N-acylation: An effective method for reducing the LUMO energy levels of conjugated polymers containing five-membered lactam units

N-acylation was studied as a method for reducing the LUMO energy levels of benzodipyrrolidone-based polymers. The N-acylated polymers showed reduced LUMO levels and improved reversibility of reductive doping compared with N-alkylated polymers. This method may also apply in other conjugated polymers with lactam repeating units.

Synthesis and thin-film transistor performance of benzodipyrrolinone and bithiophene donor-acceptor copolymers

Three novel benzodipyrrolinone-bithiophene based donor-acceptor polymers are synthesized and used as p-type semiconductors in organic thin-film transistors (OTFTs). Hole mobility of up to 0.03 cm2 V-1 s-1 is achieved. A ne

Benzodipyrrolidones and their polymers

The packing structure, thermal properties, and photophysical and electrochemical properties are presented. Some soluble benzodipyrrolidone-based small molecules were synthesized, and the first two benzodipyrrolidone- based polymers were prepared by means
