“…The Rh/POLs catalysts exhibit excellent performances in the hydroformylation of olefins, including high catalytic activity, chemo/regioselectivities, stability, and recyclability. Cui and co‐workers also successfully developed a kind of 2D chiral COFs by imine condensation of 1,3,5‐triformylphloroglucinol with diamine or triamine in the presence of catalytic amount of ( R )‐ or ( S )‐1‐phenylethylamine . After postsynthetic modification of the enaminone groups in their chiral channels with Cu(II) ions, the as‐synthesized chiral COFs can be utilized as a recyclable heterogeneous catalyst for the asymmetric Henry reaction of nitroalkane with aldehydes.…”

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, ...

Covalent Organic Frameworks: Chemical Approaches to Designer Structures and Built‐In Functions

A new approach has been developed to design organic polymers using topology diagrams. This strategy enables covalent integration of organic units into ordered topologies and creates a new polymer form, that is, covalent organic frameworks. This is a breakthrough in chemistry because it sets a molecular platform for synthesizing polymers with predesignable primary and high‐order structures, which has been a central aim for over a century but unattainable with traditional design principles. This new field has its own features that are distinct from conventional polymers. This Review summarizes the fundamentals as well as major progress by focusing on the chemistry used to design structures, including the principles, synthetic strategies, and control methods. We scrutinize built‐in functions that are specific to the structures by revealing various interplays and mechanisms involved in the expression of function. We propose major fundamental issues to be addressed in chemistry as well as future directions from physics, materials, and application perspectives.

Die Fortschritte der Chemie im letzten Jahrzehnt ebnen neue Wege zur Gestaltung organischer Polymere über Topologiediagramme. Dieser Ansatz ermöglicht das kovalente Zusammenfügen organischer Einheiten zu geordneten Topologien einer neuen Polymerform, den kovalenten organischen Gerüstverbindungen. Dies bedeutet einen Durchbruch in der Chemie, da nunmehr eine molekulare Plattform für die Synthese von Polymeren mit vorbestimmbaren Primärstrukturen und Strukturen höherer Ordnung zur Verfügung steht, ein zentrales Ziel, das über ein Jahrhundert lang angestrebt wurde, mit herkömmlichen Gestaltungsprinzipien aber nicht erreichbar war. Das neue Gebiet entwickelt seine eigenen Eigenschaften, die sich von jenen herkömmlicher Polymere unterscheiden. Unser Aufsatz fasst die Grundlagen und wichtigsten Fortschritte zusammen, wobei der Schwerpunkt auf der Chemie des Strukturdesigns liegt, einschließlich der Grundgedanken, Synthesestrategien und Kontrollverfahren. Wir prüfen integrierte, für die Strukturen spezifische Funktionen, indem wir verschiedene Wechselspiele und Mechanismen aufzeigen, die an der Expression der Funktion beteiligt sind. Wir benennen grundlegende Probleme, die in der Chemie und in zukünftigen Forschungsrichtungen der Physik und Materialwissenschaft zu adressieren sind, und beschreiben Anwendungsmöglichkeiten.
