## Description

- description: Triangulenes as neutral radicals are becoming promising candidates
    for future applications such as spintronics and quantum technologies. To extend
    the potential of the advanced materials, it is of importance to control their
    electronic and magnetic properties by multiple graphitic nitrogen doping. Here,
    we synthesize triaza[5]triangulene on Au(111) by cyclodehydrogenation, and its
    derivatives by cleaving C−N bonds. Bond-resolved scanning tunneling microscopy
    and scanning tunneling spectroscopy provided detailed structural information and
    evidence for open-shell singlet ground state. The antiferromagnetic arrangement
    of the spins in positively doped triaza[5]triangulene was further confirmed by
    density function theory calculations. The key aspect of triangulenes with multiple
    graphitic nitrogen is the extra pz electrons composing the π orbitals, favoring
    charge transfer to the substrate and changing their low-energy excitations. Our
    findings pave the way for the exploration of exotic low-dimensional quantum ph
