A polycatenated hydrogen-bonded organic framework based on embraced macrocyclic building blocks for fluorescence detection of nitrobenzene in water

Abstract

A fluorescent polycatenated hydrogen-bonded organic framework (MEP-HOF) has been developed using a C3-symmetric rigid macrocycle as the exclusive building block. Stabilised by intermolecular non-covalent interactions in the solid state, the...

Recent progress in gas separation platforms based on hydrogen-bonded organic frameworks (HOFs)

“…81 Altering either of them would significantly alter the final materials' structure. 61,[82][83][84][85][86][87][88] Only reasonably strong hydrogen bonding interactions are practical for creating stable and stiff HOFs since labile hydrogen bonds may cause polymorphism issues and flexibility, or even framework collapse due to subsequent desolvation. 15 In addition, the interactions between the components of buildings and guest molecules as well as the interactions between the building blocks and hydrogen bonds are crucial.…”

Smart organic materials based on macrocycle hosts

“…In addition to the covalently constructed porous organic materials, supramolecular organic frameworks (SOFs) and hydrogen-bonded organic frameworks (HOFs) based on macrocycles have also been successfully fabricated. Nevertheless, although these macrocycle-containing porous materials demonstrate intriguing properties, they either function in the same fashion as the adaptive molecular crystals, 135,136 or exhibit guest uptake behaviours without responsive features, 137,138 which are therefore not covered in the scope of this review.…”

Design and Synthesis of New Type of Macrocyclic Architectures Used for Optoelectronic Materials and Supramolecular Chemistry

“…Cong and co-workers described a new macrocyclic platform 25 (Figure 20). [31] The tri-carboxylated functional groups on macrocyclic skeleton formed supramolecular pairs driven by multiple CÀ H•••π interactions. These supramolecular pairs further established a H-bond organic framework .…”
