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, ...

Integrating different kinds of pores into one covalent organic framework (COF) endows it with hierarchical porosity and thus generates a member of a new class of COFs, namely, heteropore COFs. Whereas the construction of COFs with homoporosity has already been well developed, the fabrication of heteropore COFs still faces great challenges. Although two strategies have recently been developed to successfully construct heteropore COFs from noncyclic building blocks, they suffer from the generation of COF isomers, which decreases the predictability and controllability of construction of this type of reticular materials. In this work, this drawback was overcome by a multiple-linking-site strategy that offers precision construction of heteropore COFs containing two kinds of hexagonal pores with different shapes and sizes. This strategy was developed by designing a building block in which double linking sites are introduced at each branch of a C -symmetric skeleton, the most widely used scaffold to construct COFs with homogeneous porosity. This design provides a general way to precisely construct heteropore COFs without formation of isomers. Furthermore, the as-prepared heteropore COFs have hollow-spherical morphology, which has rarely been observed for COFs, and an uncommon staggered AB stacking was observed for the layers of the 2D heteropore COFs.

Porous cationic covalent triazine‐based frameworks (CTFs) with imidazolium salts as tectons were prepared via ionothermal synthesis. The high‐PF6−‐content CTF shows the CO2 adsorption of 44.7 cm3 g−1 and I2 capture capacity of 312 wt %. The influence of counterion species and contents on the porosities, CO2 adsorptions, and I2 capture capacities of the CTFs has been investigated.
