Photochromic molecules provide an intriguing and relatively untapped alternative to traditional materials utilized in organic memory devices. On page 469, Klaus Meerholz and co-workers review the use of photochromic materials, with an emphasis on dithienylethenes, in electrically-addressed organic electronic devices. Recent results for a multifunctional, light-emitting organic memory device incorporating a photochromic transduction layer are discussed in terms of applications in signage and multilevel memory arrays.
