ChemPhysChem (Impact Factor: 3.42). 10/2003; 4(10):1124 - 1127. DOI: 10.1002/cphc.200300718


Light works. The multifrequency recording of an image and the nondestructive readout using IR light on a polymer film containing two photochromic diarylethene derivatives were successively carried out. The image was recorded using two UV light wavelengths, and monitored nondestructively by using IR light at two different wavelengths (1590 cm-1, upper image; 1550 cm-1, lower image). Different images could be read out at the different wavelengths.
