The construction of an AIE-based controllable singlet oxygen generation system directed by a supramolecular strategy

An aggregation-induced emission (AIE) based smart singlet oxygen ( 1 O 2 ) generation system has been successfully fabricated based on supramolecular host-guest assembly. The controllable 1 O 2 generation can be achieved by conveniently changing the molar ratio between the macrocyclic host (WP5) and...

Description
Summary:An aggregation-induced emission (AIE) based smart singlet oxygen ( 1 O 2 ) generation system has been successfully fabricated based on supramolecular host-guest assembly. The controllable 1 O 2 generation can be achieved by conveniently changing the molar ratio between the macrocyclic host (WP5) and the guest molecule (TPEPY). Moreover, reversible control of 1 O 2 generation and fluorescence emission of supramolecular nanoassemblies can be achieved via adding Fe 3+ and EDTA, which allows qualitatively monitoring the singlet oxygen generation efficiency by the naked eye. An aggregation-induced emission based controllable singlet oxygen generation system has been successfully fabricated in an aqueous phase based on supramolecular host-guest assembly.
