Second-order nonlinear optical spectroscopy of functional dyes and supramolecular assemblies
Due to their highly polarizable electronic system, organic conjugated molecules can exhibit a remarkably strong nonlinear optical (NLO) response which will be studied in this project in view of applications in two-photon imaging and two-photon-initiated microfabrication. Using a worldwide unique measurement setup for second harmonic light scattering with tunable laser wavelength, you will examine the origin of this nonlinear response, and its pronounced resonances in the visible and near-infrared spectrum. The measurement results form the basis for theoretical models (also in collaboration with theoretical groups) and the derivation of structure-property relations which allow you to design new molecules and materials (in close collaboration with synthesis groups) with optimised NLO properties. Second order light scattering spectroscopy (incoherent second harmonic light scattering, SHLS) is complementary to two-photon absorption spectroscopy and also yields fundamentally new insights in the electronic and vibronic structure of organic molecular systems in general. Based on the extreme sensitivity of SHLS to (a)symmetry (unlike 3rd order processes such as 2PA itself), it will also be applied to characterise changes in environment sensitive probes and supramolecular order in organic nanoparticles.
