Visible Light Photolabile, Charge Convertible Poly(ionic liquid) for Light degradable Films and Carbon Based Electronics.
We report for the first time an innovative visible light photolabile poly(ionic liquid) (VP PIL) The as prepared VP PIL features low Tg (47 degC) good thermal stability (Td 284 degC) and solubility in ranges of polar solvents. Upon blue light irradiation ~452 nm) C O bonds of picolinuim units are photocleaved, and the charges of PILs are simultaneously converted from positive to negative. Taking full advantages of these excellent properties of VP PIL, a visible light degradable film for the first time is fabricated. Moreover, to demonstrate its applications in electronics, we prepared high quality VP PIL containing conductive ink for flexible interconnects and graphene electrodes for supercapacitors.
