Mechanism of oxygen doping using NaClO. a The relative doping extents in samples irradiated at SWCNT resonant absorption peaks and at the 300 nm NaClO absorption peak. Relative doping extent is defined as \(\left[ {\left( {{\mathrm{E}}_{11}^ \ast /{\mathrm{E}}_{11}} \right)_{i{\mathrm{rrad}}.} - \left( {{\mathrm{E}}_{11}^ \ast /{\mathrm{E}}_{11}} \right)_{{\mathrm{no}}\;{\mathrm{light}}}} \right]/P_{{\mathrm{irrad}}{\mathrm{.}}}\). Error bars indicate standard deviation (s.d.) from the spectral measurement noise. b Action spectrum of the doping rate constant (circles), and relative photogeneration rates of O (¹D) (triangles). Error bars indicate s.d. estimated from literature uncertainties and spectral measurement noise. c Diagram showing computed energies for reactants, products, and proposed transition state for the doping reaction in vacuum (units: kcal mol⁻¹). Note that the ether adduct is more stable than the epoxide. d Illustration of the proposed doping reaction
