摘　　要：本文合成了一种基于金属卟啉和5-溴-8-氨基异喹啉的荧光配合物,并应用于一种识别NH_3的"开-关"荧光传感器,通过紫外可见光光谱观测了该传感器的形成动力学过程。NH_3迅速与传感器中心的钴或锌结合,同时5-溴-8-氨基异喹啉(ABIQ)从环中心离去,在激发光(λ_(Ex)=365nm)照射下发出蓝绿色荧光,实现对NH_3的检测。The reagents based metalloporphyrins complex with a isoquinoline fluorophore have been synthesized and investigated as a‘turn-on＇fluorescent ammonia sensor,and observed the formation kinetics of the sensor by using UV/Vis spectra.Ammonia quickly combined with Cobalt or Zinc in the center of sensors,while the 8-Amino-5-Bromo Isoquinoline（ ABIQ） dissociated from the center of the ring,and emitted blue-green fluorescence with the irradiating of the excitation（ λ（Ex）= 365nm）,then achieving the detection of ammonia.
