Predicted Material Properties Repository and Database (CrystalDFT)

A database of computationally predicted organic material properties


Welcome to the CrystalDFT Database!


This is an ongoing open-access project that contains our group's DFT-calculated electromechanical properties of small biomolecular crystals, metal-organic frameworks (MOFs) and racemic compounds. We invite you to look through this database and pick crystals to grow and characterise for piezoelectric applications or mechanical testing. Are you a computational chemist? Download some cifs and let us know how your predicted values compare! Do you work with photosalient materials? Check out our in-silico stress-strain curves.

If you want your published or unpublished data uploaded to this database you can contact sarah.guerin@ul.ie and shubham.vishnoi@ul.ie. We also welcome feedback on the site's usability, as well as suggested/new functional crystal structures to be included in our ongoing materials screenings.
