Figure 4. All reactions were carried out on a 0.1 mmol scale with 1.0 eq. amines 1a-g and 2 mol% TANB-Py-COF in 5.0 mL CH₃CN under blue LED irradiation at room temperature in air. Isolated yield. The orange segments in the figure denote the generation rates of H₂O₂. ^aYield detected by effective carbon number (ECN) concept. COF: Covalent organic framework; LED: light-emitting diode.
