제목 Critical Factors of Diarylethene for High Performance Photo-programmable Polymer Transistor: Crystallographic Compatibility, Quantum Yield, and Fatigue Resistance
초록 We achieved the enhancement of crystallographic compatibility by locating diarylethene (DAE) preferentially in the vicinity of intercrystallite tie-chains is mainly dependent on the overall molecular volume of DAE. To precisely control each of these determining factors of DAE-embedded polymer FETs, we synthesized and systematically analyzed a series of DAE. We strategically substituted functional groups at the specific reaction site of DAE and it leads to an ideal molecular switch for high-performance photoprogrammable polymer FETs with high photoprogrammable switching ratios of 4405, as well as high electrical fatigue resistance of up to 100 photoprogrammable switching steps. Here, we argue that crystallographic compatibility, quantum yield, and fatigue resistance are three important factors that DAE should simultaneously satisfy to realize high-performance photoprogrammable polymer field-effect transistors (FETs).
