Description

technical field

[0001] The invention relates to the field of thiol detection, in particular to a preparation method and application of a novel cyclometalated iridium complex. Background technique

[0002] Sulfur dioxide (SO 2 ) is a poisonous gas in the atmosphere and can form acid rain. It is a common and serious global air pollutant. SO 2 The pollution status and toxic effects of pollutants have always been a common concern of the whole society. via SO 2 A health survey of workers exposed to the field revealed that SO 2 The main toxicity of exposure is irritation and corrosion to the respiratory tract of humans and rodents, which proves that SO 2 Pollution is associated with the occurrence of some respiratory diseases (eg bronchitis, bronchitis, asthma, emphysema, etc.). via SO 2 Toxicology experiments found that high concentrations of SO 2 Inhalation can cause DNA damage in mice, lipid peroxidation damage in various organs, protein oxidative damage, enzyme activit...
