Precise Tailoring of the Coordination Environment of Single‐Atom Cu(I) on Trifurcate AlL3 Supports for Click Chemistry

Rare Metals, EarlyView.
ABSTRACT Single‐atom catalysis hinges on fundamental challenges in precisely controlling metal‐support interactions and rationally regulating metal–adsorbate relationships. Herein, we report a universal strategy for constructing highly efficient and well‐defined Cu(I) single‐atom catalysts based on a trifurcate AlL3 molecular support.
