  • Description: Two host-guest systems have been constructed, by employing structurally similar terpyridine platinum(II) macrocycle and molecular tweezer as the synthetic receptors. The macrocycle/guest complex displays low-energy emission signal, reinforced non-covalent binding affinity, and enhanced photosensitization capability than those of the molecular tweezer/guest one. The discrepancy between macrocyclic and acyclic preorganization modes originates from the different numbers of Pt(II)Pt(II) metal–metal bonds in host-guest complexation structures.
