Abstract Inspired by the mechanical interlocking principles of traditional Chinese mortise‐and‐tenon structures, a 3D gradient supramolecular network is developed through oriented self‐assembly subphthalocyanine (SubPc‐0) arrays on La‐doped Ag 3 PO 4 (La 0.01 2.99 ). This bioinspired design synergistically combines π‐orbital topological extension with dynamic B–La coordination bonds to construct an S‐scheme heterojunction dual‐phase charge modulation capability. Mechanistic studies reveal that La 3+ doping induces anisotropic electron delocalization for directional bulk transfer, while interfacial coupling establishes ultrafast (<10 ps) atomic‐scale transport channels orbital hybridization. The optimized SubPc‐0/La system demonstrates 2.2‐ and 2.1‐fold improvements in tetracycline oxytetracycline degradation efficiencies, respectively, 94% activity retention after five cycles. Advanced characterization techniques including femtosecond transient absorption spectroscopy (fs‐TAS) Kelvin probe force microscopy (KPFM), combined theoretical calculations, elucidated intricate photocatalytic mechanism transfer pathways. work delivers effective strategy mechanistic insights stacking engineering materials.
