A photoactivated bifunctional chelating agent is used to couple chelatable ions to biomolecules, especially proteins. The photoactivatable group is preferably (1) an aryl diazirine or fluorinated diazo compound, (2) an arylnitrene, or (3) an alpha,beta-unsaturated ketone, which, when exposed to light, yield highly reactive carbenes, nitrenes, or free radicals, respectively.
光活化双功能螯合剂用于将可螯合离子与生物大分子,特别是蛋白质耦合。光活化基团最好是(1)芳基重氮或氟化重氮化合物,(2)芳基腈,或(3)α、β-不饱和酮,它们在光照下分别产生高活性的碳、腈或自由基。
