摘要：近年来,基于非共价相互作用的超分子动态组装策略为智能荧光材料的设计提供了新思路.本研究基于葫芦脲(CB[n])与芘衍生物的主客体相互作用,构建了具有多色荧光调控功能的新型超分子体系.主体大环的引入促使主客体复合物的形成,导致分子基元PPIB和PPTB的荧光发射波长以及荧光量子产率发生显著变化.值得一提的是,这种变化是动态且可逆的,通过加入客体金刚烷竞争性地结合葫芦脲大环可实现原有主客体复合物的解组装,荧光性能恢复至初始状态.基于该体系的多色荧光特性,进一步开发了双重加密荧光墨水和可重复书写-擦除的信息加密系统.本研究为基于主客体作用的动态多色荧光材料的设计及信息加密技术的开发提供了新策略.
In recent years,supramolecular dynamic assembly strategies based on non-covalent interactions have provided novel insights for the design of intelligent fluorescent materials.This study constructed a new supramolecular system with multicolor fluorescence modulation capabilities based on host-guest interactions between cucurbituril(CB[n])and pyrene derivatives.The introduction of macrocyclic hosts facilitated the formation of host-guest complexes,leading to significant changes in fluorescence emission wavelengths and quantum yields of molecular building blocks PPIB and PPTB.Notably,these changes were dynamic and reversible.By introducing adamantane guests to competitively bind with CB[n]macrocycles;the original host-guest complexes could disassemble,restoring fluorescence properties to their initial states.Leveraging the multicolor fluorescence characteristics of this system,dual-encryption fluorescent inks and rewritable-erasable information encryption systems were further developed.This research provides new strategies for designing dynamic multicolor fluorescent materials based on host-guest interactions and advancing information encryption technologies.
