Exceptional nonlinear optical (NLO) switching behavior , including an extremely large contrast (on/off) of ∼35 and high NLO coefficients, is displayed by a solid‐state reversible quadratic NLO switch. The favorable results, induced by very fast molecular motion and anionic ordering, provides impetus for the design of a novel second‐harmonic‐generation switch involving molecular motion.
