A metal-organic photoinduced electron transfer(PET) supramolecular nanoarchitecture comprised of Ru(Ⅱ) bis(terpyridine)-modified pillar[5]arene(electron acceptor) and triazole triphenylamine amyl cyanide(electron donor) has been designed and constructed.Through the comparison of diverse solvents and acceptors,the two conditions,i.e.,modification of pillar[5]arene to donor and weak polar solvent are benefit for the occurrence of "efficient PET" because of shorter D-A distance in the presence of pillar[5]arene.Crucially,the fluorescence and PET process of the supramolecular assembly could be further modulated by solvent conversion and another competitive guest.The study provides a supramolecular method to design and construct tunable PET systems and PET-based smart materials.
