A series of eight N-substituted 1,4,7-triazacyclononanes L has been prepared having combinations of hydrogen, methyl, ethyl or propyl substituents on the three nitrogens. From the monoprotonated macrocycles dinuclear manganese complexes [Mn2III(µ-O)(µ-O2CMe)2L2]X2(X = ClO4 or PF6) were prepared under anhydrous conditions in high yield. A relationship between the absorption bands and the electrochemical

Provided is a probe for detecting in vivo hydrogen sulfide, specifically, a probe for detecting hydrogen sulfide including a complex compound into which a radioactive isotope Cu is introduced. According to specific embodiments of the present disclosure, as a result of real-time observing animal models, in which hydrogen sulfide involved in various diseases is generated in a large quantity, through optical and nuclear medicine imaging, the probe for detecting hydrogen sulfide according to the present disclosure may selectively bind with hydrogen sulfide to provide images of a site where hydrogen sulfide has abnormally increased in a cell or a tissue, thereby detecting a disease in an unexpected site without affecting the anatomical properties of the body. In addition, the probe for detecting hydrogen sulfide quickly reacts with hydrogen sulfide, thereby solving the existing problem of waiting a predetermined time for testing after an imaging agent is injected. Accordingly, the probe may be effectively used as a means for diagnosing diseases, such as a composition for imaging, an imaging method, etc.
