Summary

Individual molecular catalysts in a pseudohomogeneous microenvironment have been directly explored by single-molecule observations. In this Chapter, we focus in this chapter on our proof-of-concept studies using immobilized metal-based catalysts and single-molecule fluorescence spectroscopy. Application of photostable fluorophores that signal chemical processes at the metal complex or substrate site is mandatory. Major outcomes of our research are as follows: 1. observation of the reversible formation of a single Cu(II) complex that opened a chemical approach to superresolution microscopy; 2. the irreversible epoxidation of a double–bond, exemplified by the landmark change of the emission color; 3. evidence for catalytic redox cycles of individual Cu(I/II) complexes.
