Optically probing molecular shuttling motion of[2]rotaxane by a conformation-adaptive fluorophore
文献摘要：
A bistable[2]rotaxane with a conformation-adaptive macrocycle bearing a 9,14-diphenyl-9,14-dihydrodibenzo[a,c]phenazine(DPAC)unit was synthesized,which could be utilized to optical probe the molecular shuttling motion of the functionalized rotaxane system.The UV-vis,1H NMR and PL spectro-scopic data clearly demonstrated that the DPAC ring was interlocked onto the thread and the fluores-cence intensity of the DPAC unit in the macrocycle was effectively regulated by the location change of the macrocycle along the thread under acid/base stimulation,which was attributed to the modulation of the intramolecular photo-induced electron transfer between the DPAC unit and the methyltriazole(MTA)unit.This bistable rotaxane system containing a conformation-adaptive fluorophore unit in the macrocy-cle moiety opens an alternative way to design functional bistable mechanically interlocked molecules.
