Programmable Ultralong Phosphorescent Ionogels for Intelligent Monitoring

Le résumé fourni par la source

Abstract Pure organic flexible RTP materials show broad application prospects in fields such as electronic sensing and high‐resolution displays. IGs offer advantages over conventional soft matter due to their high ionic conductivity, thermal stability, and low volatility. However, flexible IGs often fail to provide sufficient rigidity to protect triplet excitons from environmental quenching, presenting a challenge in the development of RTP‐IGs. Additionally, these materials may encounter unforeseen circumstances during operation that compromise their functional integrity, affecting real‐time monitoring effectiveness. Developing novel IG systems with excellent RTP properties and real‐time monitoring capabilities is thus urgent and meaningful. This work fabricated a novel, mechanically outstanding IG material (toughness ≈ 77.11 MJ m – 3 ) serving as an excellent matrix for flexible RTP materials. A trace doping strategy endowed these materials with ultralong full‐color RTP (afterglow >50 s, lifetime up to 5.23 s), demonstrating potential for real‐time operational state monitoring. These systems were applied in strain‐softening/hardening monitoring materials, smart conductive systems, and an intelligent thermally driven claw.
