Abstract: Fast responsive photochromic materials are obtained by encapsulation of the photoactive molecules within liquid-filled capsules. By properly selecting the nature of the liquid core, solid stable materials are prepared with solution-like color-changing rates that are at least tenfold faster than those measured for rigid polymer thin films and particles.
