Here, we demonstrate experimentally for the first time the coherent oscillation and coupling of photoactive molecules integrated randomly in a polymeric medium which act cooperatively upon irradiation with UV light. Accordingly, we showed the specular reflection and Brewster phenomenon change of photochromic molecular dipole antennas. We successfully demonstrate the concept of Brewster wavelength, which is based on the dipolar interaction between radiating dipoles and the surrounding matrix possessing a net dipole moment, as a key tool for highly localized sensing of matrix polarity. Our results enrich our understanding of coherent dipole radiation and pave the way of research based on glassy disordered dipolar composites for new application in switchable optical devices.
