Abstract

The invention provides dual-emission ratio type oxygen probes and an application and belongs to the technical field of the industry of fine chemicals. The probes are prepared from coumarin fluorophore as a main ligand and 2-pyridin-benzimidazole as an ancillary ligand. The iridium complexes have dual-wavelength emission characteristics and can be used for quantitatively detecting oxygen according to a ratio of fluorescence intensity of two emission wavebands.

Description

technical field [0001] The invention relates to a kind of double-emission ratio oxygen probe and its application, in particular to a fluorescent matrix-iridium complex which is particularly sensitive to oxygen and has double-emission properties, which belongs to the technical field of fine chemicals. Background technique [0002] Oxygen is one of the essential elements for sustaining living organisms to carry out various life activities. The use of oxygen has been widely used in various fields of society, but for most of the processes in which oxygen participates, oxygen needs to be maintained at a certain concentration, so , methods to quantitatively detect oxygen concentrations in these processes have been extensively studied. The traditional oxygen measurement methods mainly include Clark oxygen electrode method and Winkler titration method. The national standard method is Winkler titration method. Winkler titration method has the disadvantages of time-consuming, laboriou...
