An organic material undergoing light-induced phase transition comprising a diheteroarylethene compound which in a crystalline state undergoes a photochromic reaction. The diheteroarylethene compound reversibly changes in color upon irradiation with light. It comes into a liquid phase state in the course of a change from a crystalline open- ring form to a crystalline closed-ring form or in the course of a change from a crystalline closed-ring form to a crystalline open-ring form. The compound is usable in optical recording media, display panels, sensors, optical switch elements, etc. so as to take advantage of not only the color changing upon light irradiation but differences in refractive index, transmittance, etc. caused by phase changes.

L'invention porte sur un matériau organique subissant une transition de phase induite par la lumière et comprenant un composé dihétéroaryléthène qui, à l'état cristallin, subit une réaction photochromique. Le composé dihétéroaryléthène change de couleur de manière réversible lors de l'irradiation de lumière. Il se transforme en phase liquide au cours d'un changement d'une forme cristalline en anneau ouvert en une forme cristalline en anneau fermé, ou au cours d'un changement d'une forme cristalline en anneau fermé en une forme cristalline en anneau ouvert. Le composé peut être utilisé dans un support d'enregistrement optique, des panneaux d'affichage, des capteurs, des éléments de commutation optiques, etc., de façon à bénéficier non seulement du changement de couleur lors de l'irradiation de lumière, mais des différences d'indice de réfraction, de transmittance, etc., dues aux variations de phase.
