CURATED-COFs

Clean, Uniform and Refined with Automatic Tracking from Experimental Database (CURATED) COFs from literature.

This repository contains original structures from literature search, with git-tracked corrections.
DFT-optimized frameworks with DDEC charges are available on Materials Cloud.

NOTE: the crystal structures in this database may contain unnatural bond length and geometry, consistent with the CIF file reported in the original reference papers. The DFT optimization should take care of these problems and correct for them (see optimized structures on Materials Cloud). The CIF files in the present database are modified manually or programmatically only when the DFT optimization does not solve the problem and a trivial manual fix can be applied: in this case the Modifications are reported in cof-frameworks.csv. Don't hesitate to report any structure that is still problematic after the DFT optimization.

Files' structure:

  • cof-frameworks.csv contains the list of COFs and the manual modifications
  • cof-discarded.csv contains a list of COFs that have been discarded because of duplicate detection, unobserved AA/AB stacking variant, unobserved n-fold interpenetration, or other reasons reported in the document
  • cof-papers.csv contains a list of the reference papers for the COFs in the database: for example, p0701 is the reference of COFs 07010N3, 07011N3, 07012N3, and 07013N3
  • cifs/ contains all the crystallographic information files (CIFs) for the COFs listed in cof-frameworks.csv and cof-discarded.csv

The database builds on the work of Tong et al., named CoRE-COF-DT280-v2.0.
