title: Quantitative fluorescent detection of pyrophosphate with quinoline-ligated dinuclear zinc complexes.
abstract: Dinuclear zinc complex [Zn2(TQHPN)(AcO)](2+) exhibits characteristic fluorescence response (λex = 317 nm and λem = 455 nm) toward pyrophosphate (PPi) with maximum fluorescence upon 1:1 Zn2(TQHPN)-PPi complex formation. The crystallographic investigation utilizing P(1)P(2)-Ph2PPi revealed that the fluorescent response mechanism is due to intramolecular excimer formation of two quinoline rings.
