“…For example, Wang, Sun, and co-workers provided a unique example of the phenomena of interpenetration isomers based on a well-known 3D COF, COF-300 . We have developed a series of 3D COFs with different topologies by using triangular prism triptycene linkers as node centers, such as JUC-564 with a stp net, JUC-568 and JUC-569 with a ceq or acs net, and JUC-596 and JUC-597 with a hea net, and constructed the first 3D COF with the zeolitic net (ZOF-1) by combining two kinds of tetrahedral building blocks with fixed or relatively free bond angles . Although many efforts have been made, topological isomerism in 3D COFs has never been observed, which remains a great challenge.…”

Although isomerism is a typical and significant phenomenon in organic chemistry, it is rarely found in covalent organic framework (COF) materials. Herein, for the first time, we report a controllable synthesis of topological isomers in threedimensional COFs via a distinctive tetrahedral building unit under different solvents. Based on this strategy, both isomers with a dia or qtz net (termed JUC-620 and JUC-621) have been obtained, and their structures are determined by combining powder X-ray diffraction and transmission electron microscopy. Remarkably, these architectures show a distinct difference in their porous features; for example, JUC-621 with a qtz net exhibits permanent mesopores (up to ∼23 Å) and high surface area (∼2060 m 2 g −1 ), which far surpasses those of JUC-620 with a dia net (pore size of ∼12 Å and surface area of 980 m 2 g −1 ). Furthermore, mesoporous JUC-621 can remove dye molecules efficiently and achieves excellent iodine adsorption (up to 6.7 g g −1 ), which is 2.3 times that of microporous JUC-620 (∼2.9 g g −1 ). This work thus provides a new way for constructing COF isomers and promotes structural diversity and promising applications of COF materials.

“…One of the representative microporous materials is zeolites, which exhibit large surface areas (300-2000 m 2 g −1 ) that have reached a state of maturity as catalysts and adsorbents for industrial separations 31,32 . The commercialization of zeolites has been facilitated by their high thermal stability levels, which result from their strong constituent tetrahedral bonds, such as Si-O and Al-O bonds 33 . Furthermore, the crystalline properties of zeolites provide the prediction of structures and computational screening to identify ideal architectures for certain separation applications and as their modification is applied as inracellular delively for biomedical application 34,35 .…”

Nanoarchitectonics describes the integration of nanotechnology with other fields as a postnanotechnology concept that elevates it to material science. Based on this fundamental principle, we address pore-engineered nanoarchitectonics with application targets for cancer therapy by combining basic descriptions and exemplifying therapy applications in this review. The initial two sections briefly summarize pore-engineered nanoarchitectonics basics according to classification based on (i) material porosity and (ii) material composition. Afterward, the main application-oriented section—designing mesoporous material for cancer therapy—is presented. Various types of drug delivery systems, including mesoporous nanoparticles as nanocarriers, endogenous stimuli-responsive drug delivery, exogenous stimuli-responsive drug delivery, and targeted drug delivery, are described. Importantly, the clinical translation of mesoporous materials is further discussed. Mesoporous materials are unique nanoparticles that offer a network of cavities as vehicles for drug nanocarriers. Regarding the developments that allow mesoporous nanoparticles to be broadly used in clinical settings, there are several challenges that should be solved for their clinical application. From a clinical perspective, there are tremendous processes in the development of mesoporous materials.

“…Covalent organic frameworks (COFs) are a new type of crystalline porous organic material composed of organic building blocks linked by covalent bonds. 15 COFs have attracted extensive attention in different fields, such as adsorption and separation, organic electronics, heterogeneous catalysis, and so on, 16–30 due to their remarkable merits, including a large specific surface area, regular pore structure, ultra-low density, easily-controllable functional structure, and high thermal and chemical stability. More importantly, three-dimensional (3D) COF materials displayed broad benefits such as with interconnected pores and higher specific surface areas compared with their two-dimensional (2D) counterparts.…”
