Case Study of Diarylethene for High Performance Photoprogrammable Polymer Transistor |
| 초록 |
Crystallographic compatibility, quantum yield and fatigue resistance are three important factors that diarylethene (DAE) should simultaneously satisfy to realize high performance photoprogrammable polymer field-effect transistors (FETs). To precisely control each of these determining factors of DAE-embedded polymer FETs, a series of DAE is synthesized and systematically analyzed. High-mobility DPPDTT is blended with various DAE derivatives as a matrix polymer. We show that strategic substitution of functional groups at the specific reaction site of DAE can lead to an ideal molecular switch for high-performance photoprogrammable polymer FETs with high photoprogrammable switching ratios of far over 103, as well as high electrical fatigue resistance of up to 100 photoprogrammable switching steps. The physics behind the success of the optimized DAE structure is discussed in conjunction with various photophysical, structural and morphological analyses tools. |
