This strong and highly directional interaction can be exploited to develop supramolecular synthons for rational crystal design and materials development. While these XB interactions are very similar to H-bonds, they have several significant advantages, including a higher degree of directionality due to the localization of the electrophilic site, which is exactly opposite to the covalent bond to the halogen atom. The strength of the interaction is easily tunable by varying […]
