Abstract

We present the rationale, synthesis and evaluation of the first activatable fluorescent probe that utilizes fluorescence lifetime change for detection of nitric oxide. The new probe DAP-LT1 features a near-infrared polymethine skeleton with a diaminobenzene functionality incorporated into the meso-position. The probe is partially quenched, and upon reaction with nitric oxide shows an increase in the fluorescence lifetime from 1.08 ns to 1.24 ns.
