Paper Abstract

Two photochromic fulgides, 3-[2-(N, N-dimethylaniline)-5-methyl-xazolemethylene]-4-isopropylidenetetrahydrofuran-2, 5-dione (A) and 3-(1,2-dimethyl-5-phenyl-pyrrolmethylene)-4-isopropylidenetetrahydrofuran-2, 5-dione (B), doped in PMMA as candidates of dual-wavelength optical memory for parallel recording are demonstrated. With 488nm-laser and 650nm-laser, both “cross” and “star” images are recorded on the same place of the sample and readout. Cross-talk between two fulgide compounds in PMMA matrix is also investigated.
