In this study, a coordination‐driven synthetic strategy developed 3d transition metals interlamellar region layered organolead iodides with atomic precision. The resultant hybrids exhibit selective H 5 OH using O vapor at evolution rates 24.9–31.4 µmol g −1 h selectivity 89.5–93.6%, while pristine iodide yields only 1 products. Band structure calculations photoluminescence studies indicate that interlayer species greatly contribute frontier orbitals enhance exciton dissociation free carriers, facilitating between adjacent layers. addition, Bader distribution in situ experimental spectroscopic reveal asymmetric Ni–O–Pb catalytic sites intrinsic polarization, promoting coupling leading formation key *OC–CHO intermediate.
