摘要:

AbstractMolecular first‐order hyperpolarisabilities β of (donor)2‐acceptor type molecules have been determined by electric field induced second‐harmonic generation (EFISHG) experiments at 1.06 μm. The hyperpolarisability values are enhanced in these two dimensional charge transfer molecules, compared with a reference linear model molecule. One of these molecules absorbs part of the second‐harmonic beam. We propose a determination method for β that takes into account this phenomenon. Crystals of the title molecules exhibit second harmonic generation by the p
