Atomic‐Level Dipole Engineering in Covalent Organic Frameworks for Enhancement of Photocatalytic Hydrogen Peroxide Synthesis

. This rate surpasses its sulfur (HFPB-BS) and selenium (HFPB-BSe) analogues by factors of 1.2 and 3.1, respectively. This work establishes, for the first time, a direct and quantifiable correlation between heteroatom-tuned dipole polarization and photocatalytic activity, presenting a rational and powerful design principle for the next generation of advanced COF photocatalysts.
