Giving color to data recording: Upon irradiation with selected wavelengths of light the hexane solution of a fused dithienylethene derivative changes from colorless to yellow, green, black, or blue depending on the wavelength, and irradiation time (see picture). This could be a landmark in the development of new data recording materials.
