A combination of strategies for optimizing the molecular hyper‐polarizability have been employed in the design of the molecules reported here: an aromatic moiety is linked to a planar‐fixed polyene chain. The synthesis and nonlinear optical (NLO) characterization (absorption and electric‐field‐induced second harmonic generation) of the materials are described and their NLO properties compared —Favorably—with those of 4′‐dimethylamino‐4‐nitrostilbene, the prototypical organic material for electrooptic devices based on poled polymers.
