Catalytically active atomically thin cuprate with periodic Cu single sites.

ABSTRACT: Rational design and synthesis of catalytically active two-dimensional (2D) materials with an abundance of atomically precise active sites in their basal planes remains a great challenge. Here, we report a ligand exchange strategy to exfoliate bulk [Cu₄(OH)₆][O₃S(CH₂)₄SO₃] cuprate crystals into atomically thin 2D cuprate layers ([Cu₂(OH)₃]⁺). The basal plane of 2D cuprate layers contains periodic arrays of accessible unsaturated Cu(II) single sites (2D-CuSSs), which are found to promote efficient oxidative Chan-Lam coupling. Our mechanistic studies reveal that the reactions proceed via coordinatively unsaturated CuO₄(II) single sites with the formation of Cu(I) species in the rate-l
