Polymer materials have attracted much attention in recent years for an active component in the application of electronic devices. Among several types of electronic devices much attention has been paid recently to the use of electrically bistable resistive switching organic materials in the fabrication of memory devices. The development of highly stable memory devices based on dimensionally and thermally stable polyimides have been reported so far. Recently, spiropyran moieties containing polymers as a side chain have been used for switching memory effect in polymer memory devices because spiropyran molecule is a well-known photochromic units which undergo reversible structural transformation among multistates in response to external inputs such as light. In this study, we synthesized polyimide containing spiropyran moiety as a side chain, investigated switchable polymer memory characteristics by light. |
