A new class of multifunctional molecules for holographic applications is presented: the cyclopalladated complexes BEPON (see Figure) and AZPON rank among the best organic photorefractive materials known due to their excellent photoconductivity and field‐induced refractive index modulation. Upon quenching from the melt, BEPON forms an amorphous composite in which the density of active molecules is very high.
