Fluorescent sensing of transition metal ions based on the encapsulation of dithranol in a polymeric core shell architecture

摘要

The encapsulation behaviour and the resulting transition metal ion sensing capabilities of a 5-arm star-shaped polymer bearing terpyridine ligands on its periphery are described.The encapsulation of functionalities into polymeric or dendritic core shell architectures is a highly promising field of research due to the manifold application possibilities in drug delivery,stimuli responsive release,catalysis,or phase transfer.On the other hand,Patroni et al.recently described that a lipophilized ion receptor,a surfactant,and a fluorescent hydrocarbon(pyrene),are capable of forming micelles in water with the fluorophore included in them,that respond to Cu~(2+)and Ni~(2+)ions as selective fluorescent sensors.
