Structure transformation from Sierpiński triangles to chains assisted by CO and CO2 molecules

Caption

C3PC molecules and Fe atoms formed Sierpiński triangles on Au(111) through three-fold coordination interactions. After dosing CO molecule, the stable coordination Fe(C3PC)3 motifs changed to Fe(C3PC)4 with an axially bonded CO molecule, which transformed STs into one-dimensional chains. Different to the coassembly of CO with Fe(C3PC)4, CO2 molecules induced the structural transformation through a molecular catassembly process.
