Paper Abstract

We have designed a novel type of NLO-phores based on donor/acceptor (D/A)-substituted peri-arylated naphthalenes 2 with improved efficiency-transparency trade off. In contrast to the conventional one-dimensional conjugated (iD-CT) systems 1 our concept prevents a direct conjugation between the D/A-substituents instead it is based on multidimensional polarizations (e.g. 3D-CT) utilizing through-space interactions. The comparison of iD-CT systems with isomeric compounds of the nonconjugated 3D-CT type reveals much better f3- values for the latter ones. This could be attributed to more than one electronic transitions in the long wavelength region. As a result these chromophores are not limited by the two-level model.
