Dinuclear zinc complex Zn2(TQHPN)(AcO) 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.
双核锌配合物[Zn2(TQHPN)(AcO)]2+对焦磷酸盐（PPi）表现出特征荧光响应（λex=317nm 和 λem=455nm），在 1:1Zn2(TQHPN)-PPi 配合物形成时具有最大荧光。利用 P(1)P(2)-Ph2PPi 的晶体学研究表明，荧光响应机制是由于两个喹啉环的分子内激基形成。
