Cyclodextrins are torus‐shaped polymers of glucose that can bind organophosphorous compounds such as nerve agents and pesticides. We demonstrate here that cyclodextrin can bind up to two paraoxon molecules with a K av of 6775 M ‐1 . Molecular modeling shows that the paraoxon appears to bind in polar opposite orientation and have an average binding energy of −89 Kcals/mol. Published 2013.
