However, the challenge of fabricating atomically well-defined crystalline GY/GDY-based systems largely hinders detailed electronic structure characterizations. Here, we report the emergence of an unconventional band structure in mesoscopically regular (~1 {\\mu}m) metallated GDY sheets featuring a honeycomb lattice on Ag(111) substrates.
