supramolecular organic framework (SOF) based on synthetic macrocycles has been constructed in water by a self-assembly strategy. Two new organic monomers of this SOF, possessing viologen and azobenzene functional groups, form a stimuli-responsive host-guest system upon cooperatively binding with cucurbit[8]uril rings. The reversible formation and dissociation of 2D SOF can be realized by the isomerization
通过自组装策略在
水中构建了基于合成大环的二维超分子有机框架(SOF)。该SOF的两个新的有机单体具有紫精和
偶氮苯官能团,与葫芦[8] uril环协同结合,形成了一种刺激响应的宿主-客体系统。二维SOF的可逆形成和解离可以通过在紫外和可见光下将
偶氮苯异构化来实现。SOF的光响应特性是高度可逆的,并且在多达四个周期内保持稳定。此外,由大肠杆菌产生的偶氮还原酶可以还原
偶氮苯实体的N = N双键,从而导致系统的荧光恢复。作为出色而有效的荧光探针,SOF可以检测偶氮还原酶的活性,以实时监测大肠杆菌的生长过程。设想了双刺激响应2D SOF来驱动具有复杂功能的响应设备的开发。
