Effective dual-mode turn-on sensing of phosphates enabled by the twisted “head-to-head” self-assembly of Platinum(II)-terpyridyl complex with close Pt-Pt packing

The unique self-assembly of the cationic platinum( ii )-terpyridyl complex and anionic phosphates induced by short hydrogen bonding enables the aggregation-based photophysical behavior manipulation for effective dual-mode turn-on sensing of phosphates.
