摘要
Halogen bonding (XB) is a noncovalent interaction between halogen atoms, that work as electron density acceptors ( XB donors) and neutral or anionic electron density donors ( XB acceptors). It has displayed strong advantages in materials science, supramolecular chemistry, biological recognition and drug design etc. The definition, characteristics of halogen bonding and its applications in chemical sensing and molecular recognition are discussed in this review.
