Abstract
Ambipolar, narrow band gap (∼1.35 eV) fullerene-arylhydrazone dyads have been synthesized utilizing the Prato-Maggini-Scorrano reaction followed by the condensation with phenylhydrazines. Room temperature electron and hole mobilities, measured by the xerographic time of flight technique, exceed 10 −4 cm 2 V −1 s −1 at strong electric fields. The values of ionization potential, measured by the photoemission in air method, are in the range of 5.29–5.36 eV. Good ambipolar charge transport, photosensitivity across the whole visible light region of the spectrum, and solubility in common organic solvents makes these dyads attractive materials for various optoelectronic applications.
