Novel aggregation-induced charge transfer(CT) emission systems with long luminescence lifetime directed by supramolecular strategy have been successfully developed in water. The dimethylacridine-based electron donor(Br Ac) with excellent aggregation ability can co-aggregate with a triazine-based electron acceptor(TRZ) to form nanorods in water, which exhibit CT emission with long lifetime(τ = 0.92 μs).As for a similar electron donor(Qa Ac) with poor aggregation ability, water-soluble pillar[5]arene(WP5)can be introduced to promote the aggregation process, leading to the obvious CT emission with long lifetime(τ = 0.61 μs). In addition, structural modification of the acceptor with substituent groups possessing stronger electron-accepting capabilities will cause red-shift(about 50 nm) of the emission, which allows conveniently constructing long lifetime organic luminescent materials with different emission colors.

Neuromuscular blocking agents(NMBAs)are extensively used during anesthesia to improve surgical conditions by relaxing skeletal muscle movements.Rapid neuromuscular recovery after surgery is desirable to facilitate the recovery of muscle function and prevent residual blockade.Decamethonium(C10)is a classic NMBA,which has been restricted over the past decades ascribed to lack of a suitable antidote in clinic.Herein we used carboxylatopillar[6]arene(CP6A)to reverse neuromuscular blocker effect of C10 through direct host-guest encapsulation.NMR and isothermal titration calorimetry served to confirm the complexation between CP6A and C10 with robust affinity[(1.07±0.14)×10^(7)L/mol].The CP6A was further used as a reversal agent of C10,which facilitated to decrease C10 concentration in mice blood and excrete via urinary clearance,resulting in rapid recovery from muscle relaxation.These favorable outcomes might lead us to suggest that this supramolecular strategy could allow patients to regain lucidity much faster than spontaneous recovery from anesthesia.
