Noncovalent Isotope Effect for Guest Encapsulation in Self‐Assembled Molecular Capsules

Deuteration leads to stronger binding: Deuterated guests bind within the confined space of the molecular capsule more preferentially than protiated guests (see scheme). The van 't Hoff analysis of the competitive association reveals that the preferential binding of the deuterated guests is driv...

description Deuteration leads to stronger binding: Deuterated guests bind within the confined space of the molecular capsule more preferentially than protiated guests (see scheme). The van 't Hoff analysis of the competitive association reveals that the preferential binding of the deuterated guests is driven by enthalpy and opposed by entropy.
