A turn-on near-infrared fluorescent probe with rapid response and large Stokes shift for the selective and sensitive detection of zinc(ii) and its application in living cells

Herein, a new near-infrared turn-on fluorescent probe, YPT, was designed and synthesized for the rapid detection of Zn²⁺, which exhibited low limit of detection for Zn²⁺ (12 nM) as well as a favorable large Stokes shift (λ_em − λ_ex = 168 nm).
