分子受体由两个平行配置的三元-M- cl单元（M = Pd2+, Pt2+）组成，用于与芳香分子和中性方形平面Pt2+配合物形成主-客体加合物。主-客形成受几个因素控制，包括pi-pi相互作用，在某些情况下，宿主和客人之间的弱Pt-Pt相互作用。后一种相互作用通过比较Pt2-和Au3+等电子配合物与Pt2+受体形成的加合物的主客体稳定性来检验。一直以来，前者更稳定。
Molecular receptors consisting of two parallel-disposed terpy-M-Cl units (M = Pd2+, Pt2+) are used to form host-guest adducts with aromatic molecules and with neutral square-planar Pt2+ complexes. Host-guest formation is controlled by several factors including pi-pi interactions and, in some cases, weak Pt-Pt interactions between the host and the guest. This latter interaction was examined by comparing the host-guest stability of adducts formed by isoelectronic Pt2- and Au3+ complexes with the Pt2+ receptor. Consistently, the former is more stable.
