Covalent organic frameworks (COFs) are porous crystalline polymers that result from the
formation of covalent bonds between precisely assembled organic units. Linkage chemistry …

Organic photochemistry is intensely developed in the 1980s, in which the nature of excited
electronic states and the energy and electron transfer processes are thoroughly studied and …

Covalent organic frameworks (COFs) attract significant attention due to their ordered,
crystalline, porous, metal‐free, and predictable structures. These unique characteristics offer …

As a key structural parameter, phase depicts the arrangement of atoms in materials.
Normally, a nanomaterial exists in its thermodynamically stable crystal phase. With the …

Although C–H functionalization is one of the simplest reactions, it requires the use of highly
active and selective catalysts. Recently, C–H-active transformations using porous materials …

Covalent organic frameworks offer a molecular platform for integrating organic units into
periodically ordered yet extended two-and three-dimensional polymers to create …

Synthetic chemists have developed robust methods to synthesize discrete molecules, linear
and branched polymers, and disordered cross-linked networks. However, two-dimensional …

Covalent organic frameworks (COFs) have entered the stage as a new generation of porous
polymers which stand out by virtue of their crystallinity, diverse framework topologies and …

In the light of increasing energy demand and environmental pollution, it is urgently required
to find a clean and renewable energy source. In these years, photocatalysis that uses solar …

Covalent organic frameworks (COFs) are a class of crystalline porous organic polymers with
permanent porosity and highly ordered structures. Unlike other polymers, a significant …
