Photorefractive polymers have gret potential in applications such as all‐optical switching and optical communication. Here, new charge‐transporting polymers are presented based on a polysiloxane backbone with pendant carbazole groups, which provide both transport and room‐temperature poling properties without the need for additional plasticizing components. A quantitative evaluation of the phase behavior of holographic gratings based on the new materials is also presented.
