WebThe "glove effect" in the chiral pockets was proposed to explain the correlations between the steric effect of functional groups and performance of FHMOFs. Moreover, the neighborhood component analysis and RDkit/MACCS MFs show the highest predictive effect on enantioselectivities among the 4 ML classification algorithms with 9 MFs that were tested.
