A new NLO standard has been set by compound 1 for the substance class of analines: Their second‐order polarizability β is two orders of magnitude higher than that of the one‐dimensional NLO prototype p ‐nitroaniline. This is an example of the optimization of nonlinear optical chromophores with a threefold axis of symmetry, a current challenge for synthetic organic chemistry.
