Abstract:

A biradical TN3 was synthesized, which is composed of a fully substituted triphenylmethyl radical and a nitroxide. EPR spectrum of TN3 at room temperature  consists of an asymmetric quartet broad lines, suggesting its typical biradical structure. Using- ascorbate as a model compound, we proved that TN3 can be used to evaluate redox status and oxygen level simultaneously.
