The properties and applications of colloidal sol nanomaterials are largely affected by their crystallinity, making the rapid screening crystallinity important to explore diverse advanced nanomaterials. Yet, rational design a novel technique for analysis remains great challenge. In this study, we synthesized an imidazole-anchored naphthalene diamine (IANA) fluorophore with planar motif. Using IANA as fluorescence probe, demonstrated direct in model layered materials (cadmium–aluminum double hydroxides, CdAl-LDHs). crystallinity-promoted quenching is attributed crystallinity-enhanced ordered arrangement Cd-imidazole coordination, which benefits its face-to-face π–π stacking inhibits absorption ultraviolet light. Without drying treatment, directly reveals information CdAl-LDHs. addition, practical application proposed verified accurate determination CdAl-LDHs sample unknown crystallinity. This work has opened new avenue exploring alternative X-ray diffraction even organic crystals through stacking-regulated fluorescence.

Abstract Internal electric fields (IEF) have been recognized as an efficacious driving force to improve the reactivity of photocatalysis. However, manageable modulation IEF in homojunction remains a great challenge. Herein, local phosphorization strategy by precisely controlling phosphorus (P) atom doping location is presented modulate orientation smartly high‐low crystalline carbon nitride (g‐C 3 N 4 ) homojunction. Different found guide different photocatalytic reaction paths. By incorporating P low‐crystalline g‐C (P‐LCN), modulated directing from P‐LCN high‐crystalline (HCN), which contributes S‐scheme mechanism over P‐LCN/HCN Conversely, HCN (P‐HCN) modulates LCN/P‐HCN reversing P‐HCN (LCN), and follows type‐II mechanism. Profiting effective photocarriers transfer separation dynamics, especially favored electrons reducing capacity, performs superior H 2 evolution (12.09 mmol·g −1 ·h than (4.53 ). Even 3% NaCl solution real seawater, still exhibits incredible production rates 8.45 4.61 , respectively. This study unravels modulating principle phosphorization‐dependent for first time opens potential enhancing efficiency
