title: Azide conjugatable and pH responsive near-infrared fluorescent imaging probes.
abstract: The synthesis and photophysical characteristics of a pH responsive near-infrared fluorescence imaging probe is described. A key feature is the ability to conjugate the probe by an alkyne-azide cycloaddition reaction and its reversible response of fluorescence intensity across the physiological pH range.
