The combination of electrical and nonlinear optical (NLO) properties in one material is described for the tetracyanoquinodimethane (TCNQ) radical ion paired with N ‐methylstilbazolium‐based chromophores. One of the resulting hybrid materials has a conductivity of 2.3 × 10 −3 Ω −1 cm −1 and a second‐harmonic generation efficiency 45 times that of urea. During the predicted transition from electronics to photonics, optoelectronics, which requires multiproperty materials such as those described here, will play an important role.
