Abstract
The synthesis of a novel π-conjugated trinaphthylamines series is described. These original push−pull octupolar systems exhibit large two-photon action cross section (σϕ up to 510 GM) increased by a factor of 2−3 as compared to their triphenylamines analogues. This substantial improvement of the two-photon absorption properties is attributed to the stronger donor character of the trinaphthyl core.Keywords
