Single diarylethenes photochromic (DAE) molecules, sandwiched between two electrodes, can be considered as single-molecular resistor with optically modulated resistance. Changing of functional groups of DAEs allows efficient modification of their operation parameters.[1] When chemisorbed [2] or physisorbed [3] on a metallic surface, DAE form monolayers with large surface density of active switches. This allows the development of ultra-compact data storage devices in which a single molecule serves as a single bit of information. Writing information can be accomplished by means of an electric field at the molecular scale whereas the information can be erased by irradiation with UV/visible light.[4] Besides MCBJ and STM, DAEs have been used successfully for producing of flexible macro-resistors also with optical control. Experimental studies of an assembly of DAE sandwiched between a macroscopic, non-symmetric Au–reduced graphene-oxide electrode pair revealed excellent reversible conductance switching induced by UV-/visible light irradiation even under mechanical and thermal stress.
