title: 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 Zn(2+) 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.
