Donor–acceptor substituted nonlinear optical (NLO) chromophores possessing large molecular hyperpolarizabilities and chemical and thermal stabilities are of interest because of their potential applications in high‐speed electro‐optic devices. Here, a series of chromophores is presented with a diethylamino group as donor and a variety of strong electron withdrawing groups on the chromone moiety. Incorporation of these chromophores into a polyimide gives a material with high E‐O coefficients, low optical loss, and good thermal stability.
