Synthesis of C60-diphenylaminofluorene dyad with large 2PA cross-sections and efficient intramolecular two-photon energy transfer

Abstract

The first, highly two-photon active C60 derivative comprised of a A-sp3-D conjugate structure was synthesized showing effective two-photon absorption cross-sections (σ2′ = 196 ×10−48 cm4 sec−1 molecule−1) in the nanosecond regime among the best values for diphenylaminofluorene-based AFX chromophores.
