Synthesis, structure and second-order nonlinear optical properties of highly functionalized 6-aminopentafulvenes
Abstract
Novel donor–acceptor functionalized pentafulvenes have been synthesized and characterized. Structural data have been obtained by single crystal X-ray diffraction. Their molecular and macroscopic second-order nonlinear optical properties have been investigated,via electric field induced second harmonic generation (EFISH) in solution and by second harmonic generation with evanescent wave (SHEW) in the solid state.
