Design and Synthesis of NLO Efficient Organometallic Molecules.

Second-order nonlinear optical (SO-NLO) properties of group 8 half-sandwich organometallic complexes have been intensively studied throughout the last 15 years, making this class of compounds relevant for the continuous search of NLO materials. This contribution surveys the ongoing efforts to design, characterize and optimize the NLO properties of this class of compounds. Computational studies, namely DFT calculations, were performed for several model molecules in order to predict the first hyperpolarizabilities and to support experimental evidences.
