Air-stable, narrow-band-gap ambipolar C60 fullerene-hydrazone hybrid materials.

Fullerene-hydrazone dyads have been synthesized using the Confalone reaction followed by condensation with phenylhydrazines. Room-temperature xerographic time-of-flight, ionization potential, and cyclic voltammetry measurements indicate that these narrow-band-gap (E(g)<1.5 eV), ambipolar charge-transporting dyads with balanced hole- and electron mobilities, which operate in air, are attractive materials for various optoelectronic applications.
