a Schematic diagram of FeM DACs preparation procedures (FePc: iron phthalocyanine; 2-MeIM: dimethylimidazole; P123: polyethylene oxide–polypropylene oxide–polyethylene oxide). HAADF-HRTEM images of b FeMn DACs, c FeFe DACs, d FeCo DACs, e FeNi DACs, f FeV DACs and g FeCu DACs. h–m 3D atomic resolution map of the Fe-M sites. Analysis of the intensity profile of two adjacent atoms of n FeMn DACs, o FeFe DACs, p FeCo DACs, q FeNi DACs, r FeV DACs, and s FeCu DACs (blue rectangle: DACs, yellow circles: SACs).
