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. 相似文献
