|Abstract:||Two new fullerene-fluorene dyads, N-methyl-2-(2-fluorenyl)-3,4-fuller-pyrrolydine (1) and N-methyl-2-(2-fluorenyl)-3,4-fullerpyrrolydine (2), were synthesized and their structures were confirmed by MALDI-MS, 1H NMR and FT-IR. Their electrochemical and optical properties were investigated by cyclic voltammetry and Z-scan technique, including, electronic potentials, two-photon absorption cross-sections (σ2), nonlinear refractive indexes (n2), microscopic second-order hyperpolarizabilities (γR) and third-order nonlinear susceptibilities (χI (3) and χR (3)). Importantly, the χI (3) and σ2 in 2 were increased above 35% due to fullerene unit than that of 1. © 2010 Elsevier B.V. All rights reserved.|
