Multicolor oligothiophene-based light-emitting diodes

“…Electron affinities have been estimated from the reduction potentials measured by cyclic voltammetry. 9͑a͒,9͑b͒, 10 The obtained values are more than 0.5 V larger than those reported for the corresponding unsubstituted compounds. Such a large increase is correlated to the presence of the strongly electronegative sulfonyl groups.…”

“Solid state charge trapping”: Examples of polymer systems showing memory effect

“…Charge trapping is often observed in conjugated polymers, when the potential scan covers the whole range where both p-and n-doping occur [1][2][3]. Different processes can lead to charge trapping phenomena and many examples have been reported in the literature [4][5][6][7][8][9][10][11][12][13][14][15][16].…”

Toward Functionalized Conducting Polymers: Synthesis and Characterization of Novel β-(Styryl)terthiophenes

“…A number of these applications require tailored electronic properties, which influence polymer characteristics, such as p- or n-type doping, redox cycling, band gap, , and photovoltaic behavior. , Typically, aromatic substituents have been utilized in this regard. Thus, poly(3-arylthiophenes) ( 1 ) have improved doping capacity and cyclability over polythiophene, , and fusing benzene to thiophene leads to poly(isothianaphthene) ( 2 ), the prototypical small band gap polymer …”
