Vacuum Synthesis of Magnetic Aluminum Phthalocyanine on Au(111) — Chao Li and •Yongfeng Wang — Key Laboratory for the Physics and Chemistry of Nanodevices, Department of Electronics, Peking University, Beijing 100871, China.

Air-unstable magnetic aluminum phthalocyanine (AlPc) molecules are prepared by an on-surface metalation reaction of phthalocyanine with aluminum (Al) atoms on Au(111) in ultrahigh vacuum. STM/STS experiments and DFT calculations show that an unpaired spin is located on the conjugated isoindole lobes of the molecule rather than at the Al position. These results demonstrate the success of the vacuum synthesis of an air-unstable magnetic molecule. It is interesting and important to synthesize other pristine reactive MPc molecules and study their particular properties.
