Hexagonally ordered covalent organic frameworks (COFs) are interesting new crystalline porous materials that have massive potential for application in gas storage.
In the case of COFs, the vapor-assisted conversion approach was introduced by Bein and co-workers in 2015 as a scalable method for the production of thin films of COF-5 and BDT-COF.
However, the confirmation of active center and the mechanism of charge storage in COFs supercapacitors is still a significant challenge. Here, a series of Tp-based COFs with different link units have been obtained through Schiff base reaction.
Synthesis strategies, structural design, and energy storage mechanisms exhibited by COFs are systematically analyzed and presented.

Triphenylene (TP) based materials have experienced a great expansion in the latest years. TP molecules have interesting optoelectronic properties, arising from the aromatic core, which have been exploited in functional two-dimensional (2D) Metal-Organic Frameworks (MOFs) and Covalent Organic Frameworks (COFs) aside other organic polymers.
This comprehensive review delves into the myriad applications of COFs in the field of electrochemical energy storage devices. With the ever-increasing demand for high-performance energy storage solutions, COFs hold the potential to revolutionize the energetic field, captivating researchers and enthusiasts alike.
Generally, COFs-based materials offer unique advantages in terms of tunable structure, electrochemical performance, and environmental impact compared to traditional materials. However, the choice of energy storage material should be application-specific, as each material has its own set of advantages and limitations.
In addition, their excellent electrical conductivity allows for efficient electron transport within the COF structure, reducing internal resistance in energy storage devices. Lower internal resistance results in higher power output and better overall performance of batteries and supercapacitors.
