Covalent organic frameworks (COFs) are an exciting class of porous materials that have been explored as energy-storage materials for more than a decade. This review discusses efforts to develop these materials for applications in gas and electrical power storage. Some of the design strategies for developing the gas sorption properties of COFs and mechanistic studies on their formation are also discussed.

The previous studies have indeed revealed that, although the combination of tetraphenylethene-based D 2h -symmetrical monomers and linear linkers resulted in dual-pore COFs, [34][35][36][37] the formation of single-pore COFs was also observed when building blocks having the same symmetry but different structures were used. However,e ach of these two strategies theoretically can lead to two types of COFs with different topological structures.…”

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.

“…Recently, Bein and co-workers investigated the dual-pore COF platform for the realization of highly crystalline, robust frameworks. [20] The study focused on the role of the 1,1,2,2-tetraphenylethene, ETTA, subunit in promoting the formation of COF structures with high structural definition. The special propellershaped ETTA unit was identified as a specific docking site for the consecutive layers leading to the formation of well-defined molecular ETTA columns, thus demonstrating the formation of highly crystalline structures.…”

Hierarchical functional materials with properties encoded for a defined functionality such as light‐induced charge separation are highly desirable targets of numerous synthetic efforts. In the field of reticular chemistry, 2D covalent organic frameworks are an emerging class of porous and crystalline materials obtained by bottom‐up condensation of molecular building blocks assisted by non‐bonding interactions. In this research news article, an overview is provided on newly emerging photoactive and conducting 2D covalent organic frameworks, sketching the creative trajectory from subunit design strategies to framework construction and resulting functionalities.
