A stable hydrogen-bonded organic framework (HOF) for selective fluorescence sensing of neomycin sulphate

As a new class of porous crystalline materials, hydrogen-organic frameworks (HOFs) have attracted lots of attention in a variety of applications. Despite their potential, hydrogen-bonded organic frameworks (HOFs)-based fluorescent sensing materials have received relatively limited research attention to date. In this work, we successfully constructed a fluorescence sensor based on HOFs constructed by 1,3,6,8-tetrakis[ p -benzoic acid]pyrene, which can display high sensitivity and fluorescence quenching selectivity for neomycin sulphate (NS).
