It is in urgent to develop efficient and safe removal methods for Organophosphorus flame retardants(OPFRs) that are applied in many consumer products and are widely distributed in water. As adsorption is chosen as a competitive method with its simple operation and low cost, porous metal-organic-frameworks (MOFs) have been developed. However, their coordination bonds resulted in unsatisfactory stability in water. Therefore, new framework development for effective adsorption is still in progress. Here, the successful removal of OPFRs from water by 3-dimensional molecular metamaterials are reported. The molecule, through its secondary interaction, creates the regular and periodic pores in a unique way of intermolecular self-assembly, and the capillary force by regular pores can quickly eliminate OPFR. The novel 3D porous structure can only take OPFRs, not water, so that it can easily remove OPFRs in a minute without any other process. |
