Dear Muhammad Asad sorry to see that your very interesting technical question has not yet received any qualified answers from experts in the field. We are synthetic inorganic chemists, so that I'm certainly not a proven expert here. However, I would like to suggest to you a few potentially useful literature references which might help you in your analysis. Please have a look at the following articles:

Two-dimensional Covalent Organic Frameworks as Platforms for Renewable Energy and Environmental Application

This is a freely accessible PhD thesis which containT a good introduction to the field (please see attached pdf file). Also please check:

Semiconducting 2D Triazine-Cored Covalent Organic Frameworks with Unsubstituted Olefin Linkages

Article Semiconducting 2D Triazine-Cored Covalent Organic Frameworks...

This article has been posted by the authors as public full text on RG, so that you can freely download it as pdf file. The following paper also seems to be quite interesting:

Building a Consistent and Reproducible Database for Adsorption Evaluation in Covalent–Organic Frameworks

This paper is not accessible as public full text. However, three of the authors have RG profiles, so that you can easily contact one of them directly via RG and request the full text. Most often authors respond quite rapidly to such fulld text requests.

I hope this helps. Good luck with your work and best wishes, Frank Edelmann

Respected Professor Frank T. Edelmann ,thank you so much for your kind suggestions.
