have triggered serious threats to the survival and development of mankind. Consequently, exploring novel materials with task-specific applications is of fundamental importance for the sustainable development of economy and society. The burgeoning progress of nanomaterials in recent years has demonstrated that porosity is one of the essential factors in determining material properties for possible breakthroughs in their applications. Therefore, porous materials are playing important roles in many well-established applications and emerging technologies for challenging social and economic issues due to their intrinsic characteristics of large surface areas, open channels, and the possible control over the pore environment. According to International Union of Pure and Applied Chemistry, the pores of porous materials are classified into three categories by their pore sizes: micropores are smaller than 2 nm, mesopores are in the range of 2-50 nm, and macropores are larger than 50 nm. [1] Their pore walls include the organic skeleton (e.g., porous polymers, organic porous cages, and supramolecular organic frameworks), the inorganic skeleton (e.g., zeolites, porous carbons, and mesoporous silica), and the hybrid skeleton (e.g., metal-organic frameworks (MOFs)).Among the developed porous materials, porous polymers have attracted an increasing level of research interest owing to their potential to integrate the advantages of both porous materials and polymers. [2,3] Table 1 lists the characteristic structural features and properties of porous polymers, and gives a systematic comparison to other typical porous materials, such as zeolites, porous carbons, and MOFs. Porous polymers, zeolites, porous carbons, and MOFs share a number of features such as high permanent porosities, large surface areas, and designable pores and voids. However, they are different in several important aspects. The major advantages of porous polymers over many other porous materials are their chemical diversity and easy processability. Compared to zeolites and porous carbons, the synthesis of porous polymers is generally more versatile and can be approached in a way that conforms to the concept of rational materials design. Similar to MOFs, porous polymers inherit the excellent chemical and physical tunability afforded by the versatility of organic chemistry. Furthermore, Exploring advanced porous materials is of critical importance in the development of science and technology. Porous polymers, being famous for their all-organic components, tailored pore structures, and adjustable chemical components, have attracted an increasing level of research interest in a large number of applications, including gas adsorption/storage, separation, catalysis, environmental remediation, energy, optoelectronics, and health. Recent years have witnessed tremendous research breakthroughs in these fields thanks to the unique pore structures and versatile skeletons of porous polymers. Here, recent milestones in the diverse applications of porous polymers are presented, ...

“…The incorporation of the specific features of IL into the porous feature of polymer monoliths might provide promising improvement in monolithic columns performance. In this regard, an IL incorporated polymer monolith has been developed by copolymerizing 1‐allyl‐3‐methylimidazolium chloride and TMPTA as functional monomers, EDMA as the cross‐linker in a binary porogenic mixture containing 1‐propanol and 1,4‐butanediol . While the monoliths without IL exhibited poor resolution and low separation efficiency, the addition of IL to the polymerization mixture provided increased resolution and efficiency for small molecule separation.…”

“…They are usually liquid at room temperature and they have been termed as “green solvents” due to their properties such as high thermal stability, negligible vapor pressure, solvating ability, noncombustibility, nonvolatility, and mobility. Due to their unique properties, their use has attracted considerable interest, including an increasing number of publications on their use in preparing stationary phases of HPLC . An active research is found in many reports on the role of ILs to modify the retention of different types of solutes in LC .…”

A convenient and versatile method was developed for the separation and detection of alkaline earth metal ions by ion chromatography with indirect UV detection. The chromatographic separation of Mg , Ca , and Sr was performed on a carboxylic acid base cation exchange column using imidazolium ionic liquid/acid as the mobile phase, in which the imidazolium ionic liquid acted as an UV-absorption reagent. The effects of imidazolium ionic liquids, detection wavelength, acids in the mobile phase, and column temperature on the retention of Mg , Ca , and Sr were investigated. The main factors influencing the separation and detection were the background UV absorption reagent and the concentration of hydrogen ion in ion chromatography with indirect UV detection. The successful separation and detection of Mg , Ca , and Sr within 14 min were achieved using the selected chromatographic conditions, and the detection limits (S/N = 3) were 0.06, 0.12, and 0.23 mg/L, respectively. A new separation and detection method of alkaline earth metal ions by ion chromatography with indirect UV detection was developed, and the application range of ionic liquids was expanded.
