Achieving precise control over the construction of efficient charge transport channels through self-assembly engineering represents a highly effective strategy for synthesis organic supramolecular photocatalysts. Herein, tetragonal zinc meso-5,10,15,20-tetra(4-pyridyl) porphyrin (ZnTPyP) nanorods (T-ZnTPyPs) and hexagonal ZnTPyP nanowires (H-ZnTPyPs) were synthesized by varying assembly temperature. H-ZnTPyPs demonstrated photocatalytic hydrogen production rate (183 mmol/g/h) that was 14.62 times greater than T-ZnTPyP (13 mmol/g/h). This significantly enhanced activity is primarily attributed to distinct well-defined molecular arrangements H-ZnTPyPs, which support continuous linear long-range electron transfer pathways π-π stacking. Conversely, heat manipulation used in T-ZnTPyPs limits participation water molecules crystalline stacking arrangements, leading lattice distortions disrupt interactions impede pathways. research presents novel modulating optimize

Abstract Piezoelectric catalysis for tumor treatment is an emerging method generating reactive oxygen species (ROS). However, the development and optimization of piezoelectric catalytic nanomaterials remain major challenge. Herein, by regulating internal surface defects graphene phase carbon nitride (defect‐engineered g‐C 3 N 4 ), its piezoelectricity sonocatalytic performance enhanced, thus achieving efficient treatment. By reducing bulk defects, charges excited ultrasound (US) within defect‐engineered can migrate more rapidly to material surface, thereby enhancing their participation in redox reactions. Increasing not only introduce active sites on but also enhance asymmetry structure, resulting excellent properties. This nanosheet effectively generate ROS cells induce cell apoptosis under US stimulation. work introduces a expands potential application materials
