  abstract  = {Main objectives of the present dissertation can be divided in two parts. The first part deals with setting up a spectroscopic technique for reliable and accurate measurements of the two-photon absorption (2PA) cross section spectra. In the second part, this firmly established experimental technique together with conventional spectroscopic characterization, quantum-chemical computations and theoretical modelling calculations was combined and therefore used as a tool to gain information for the so-called structure-property relationship through several molecular compounds.},

  abstract  = {Efficient quadrupolar chromophores (A-pi-A) with triarylborane moieties as acceptors have been studied by the Marder group regarding their non-linear optical properties and two-photon absorption ability for many years. Within the present work, this class of dyes found applications in live-cell imaging. Therefore, the dyes need to be water-soluble and water-stable in diluted aqueous solutions, which was examined in Chapter 2. Furthermore, the influence of the pi-bridge on absorption and emission maxima, fluorescence quantum yields and especially the two-photon absorption properties of the chromophores was investigated in Chapter 3. In Chapter 4, a different strategy for the design of efficient two-photon excited fluorescence imaging dyes was explored using dipoles (D-A) and octupoles (DA3). Finding the optimum balance between water-stability and pi-conjugation and, therefore, red-shifted absorption and emission and high fluorescence quantum yields, was investigated in Chapter 5},
