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.
由两个平行排列的三联吡啶 - M - Cl单元（M = Pd2 +、Pt2 +）组成的分子受体用于与芳香族分子以及中性平面正方形Pt2 +配合物形成主客体加合物。主客体的形成受多种因素控制，包括π - π相互作用，在某些情况下还包括主体与客体之间的弱Pt - Pt相互作用。通过比较等电子的Pt2 +和Au3 +配合物与Pt2 +受体形成的加合物的主客体稳定性，研究了后一种相互作用。一致的是，前者更稳定。
