Quadrupolar chromophores for voltage sensing and white-light generation.
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).
