Concentration and acid–base controllable fluorescence of a metallosupramolecular polymer†
Abstract
A metallosupramolecular polymer (MP-Zn) bearing dibenzo-24-crown-8 (DB24C8) arms is constructed by coordinating Zn2+ with a conjugated bis-terpyridine ligand, which indicates concentration-dependent emissions from cyan to white to yellow. Successively, reversible emissions are realized by acid–base controllable recognition of DB24C8 moieties in MP-Zn with dialkylammonium ion centers.
