Oligothiophenes electron affinities

Poly- and oligothiophenes are generally p-type (hole-transporting) semiconductors. In thiophene-S,S-dioxide (98AM551 98JOC5497), this modification results in de-aromatization of the thiophene unit and increases the electron affinity and electron-transport properties of the... [Pg.307]

L6pez Navarrete et al. reported that the introduction of cyano groups in an oligothiophene as presented in 2.83 enhances the electron affinity of the oligomers, which stabilizes the radical anions or dianions and promotes them to prospective n-channel materials [176]. The application of some of these dicyano derivatives in OFETs has been reviewed [177]. [Pg.29]
