COMPAS-4: A Data Set of (BN) 1 Substituted Cata -Condensed Polybenzenoid Hydrocarbons─Data Analysis and Feature Engineering

-PBH isomers up to 6 rings, calculated at both the GFN1-xTB and density functional theory (DFT) (CAM-B3LYP/def2-SVP) levels of theory. We investigate the influence of BN-substitution on various molecular properties, including their molecular orbital energies and aromaticity, and define specific structural features that determine these properties. Notably, all of these features are chemically intuitive and simple to extract from the structure of the molecule, without any prior computation. We find that the most influential feature is the number of rings whose cyclic delocalization is disturbed as a result of the substitution.
