Inducing Radicality in Gold‐Coordinated Porphyrinoids Through Precise Tip‐Induced Covalent Bond Dissociation

π-Extended porphyrinoids are versatile platforms for the emerging field of π-electron magnetism in conjugated systems. However, achieving controlled bond-selective transformations that enable tuning of their electronic ground states remains a major challenge. Here, we propose a p...

Tunable Oxygen Connectivity in Carbaporphyrinoid Polymers on Metal Surfaces

ABSTRACT Controlling oxygen‐mediated connectivity at metal surfaces offers a powerful route to engineer covalent and metal–organic architectures with atomic precision. Here, we demonstrate tunable oxygen‐based connectivity in carbaporphyrinoid polymers on Au(111) under ultrahigh...
