A turn-on fluorogenic Zn(II) chemoprobe based on a terpyridine derivative with aggregation-induced emission (AIE) effects through nanofiber aggregation into spherical aggregates

5 October, 2014 - 09:54

Chem. Commun., 2014, Advance Article
DOI: 10.1039/C4CC05283H, CommunicationSung Ho Jung, Ki-Young Kwon, Jong Hwa Jung
The self-assembly of the terpyridine-based ligand exhibited strong emission in the presence of Zn2+ due to the formation of coordination bonds between the terpyridine moieties and the Zn2+ by the aggregation-induced emission effect.
