A few‐state model predicts that spectral properties of some quadrupolar chromophores are affected by the application of static electric fields. These dyes can monitor neuronal activity (action potential), as a sensitive and versatile alternative to classical dipolar dyes and can also be used in organic LEDs: color‐tunable and/or white‐light emission is obtained by varying the working voltage (see chromaticity diagram).
