Summary:[Display omitted] •Monomers developed in recent years for preparation of TFC membranes is summarized.•The relationship between monomer structure and membrane properties is established.•The application problems of the IP monomers are summarized.•The outlook for future development of the monomer is also discussed. The thin-film composite (TFC) membranes fabricated by interfacial polymerization (IP) can be applied in the fields of nanofiltration (NF) and reverse osmosis (RO), which has the unparalleled advantages, such as high selectivity and permeability, small capital investment and low energy consumption, thus attracting great research interest in industry and academia field. The performance of TFC membranes is determined by their microstructure and physicochemical properties while IP monomer plays a decisive role regarding both. Over the past few decades, the researchers have paid intensive and sustained efforts to develop new IP monomers. This paper reviews these monomers and the corresponding membranes developed in recent years with the aim of establishing an intrinsic relationship between monomer structure and membrane properties. The excellent performances based on new monomers in enhancing the permeability, selectivity, anti-fouling and chemical stability of NF and RO membranes for liquid treatment are highlighted. Finally, various problems in the monomer development are summarized and the outlook for future development is also discussed.
