Photochromic Materials: Photochromic Transduction Layers in Organic Memory Elements (Adv. Mater. 3/2013)

Abstract

Photochromic molecules provide an intriguing and relatively untapped alternative to traditional materials utilized in organic memory devices. , 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.

Multicolor and Multistage Response Electrochromic Color-Memory Wearable Smart Textile and Flexible Display

“…Materials with temperature-, electricity-, and optics-sensitive discoloration properties have been applied in buildings, − switches, memory devices, − sensors, batteries, , and displays. − The information change in electrochromic materials is easily controlled by the “turn-on–turn-off external voltage”. Recently, electrochromic memory materials have received widespread attention because they can retain color or signal information without continuous power input. − They are considered promising for display stability and reducing energy consumption, which has accelerated their development and potential application.…”
