Zusammenfassung:A thermally stable polyimide (PI-SP) was designed as a functional material for the fabrication of memory device, and its optoelectrical dual-mode memory was studied. In an Al/PI-SP/Al device, the memory can be switched on with the negative or positive voltage with the on/off current ratios of about 104. Besides, the PI-SP can also undergo the reversibly photochromic reactions in solution or solid state with high fatigue resistance, which can serve as optical recording material. The PI-SP based device can exhibit the electrical and optical switching properties independently, while their cooperative switching properties cannot be realized simultaneously.
