Summary

This project is aimed to continue the exploitation on the synthesis of new molecular organometallic materials and to initiate the very new field of synthesis of helical organometallic polymeric materials in view of their nonlinear optical properties (NLO). The new organometallic molecular materials will be prepared by coordination of ligands based on a broader of heteroaromatic rings with different spacer groups. The new organometallic polymeric materials will be prepared by the synthesis of helical systems based on the quiral tetrathia-[7]-helicene curve ligand. Computational calculations by DFT will be performed in model target molecules as guideline for the molecular design. All the compounds will be fully characterized by elemental analysis, current spectroscopic techniques, cyclic voltammetry and of X-ray diffraction. Analysis of all the experimental data will allow us to screen compounds for physical measurements of NLO properties.
