The oxidizing ability of peroxodisulfate upon complexation inside the Bambusuril macrocycle cavity is inhibited. This dianionic agent can be released on demand from its stable 1:1 complex in water (log K-a = 6.9 M-1) by addition of a more strongly bound anion, such as iodide (log K-a = 7.1 M-1), which can also be delivered in situ upon irradiation from a 4-hydroxyphenacyl iodide derivative with spatial and temporal precision. The oxidizing properties of peroxodisulfate ions liberated from the complex recover and can take part in subsequent chemical transformations.
