Self-organizing domino-like superlattices through stereochemical recognition match at the organic-inorganic interface in solution

Robust, fluorescent, domino-like superlattices of ultrathin nanoplates of alkaline earth halides (e.g., BaFCl) were obtained from a straightforward solution synthesis through the stereochemical recognition match at the organic-inorganic interface, which was demonstrated by both well-designed experiments and a molecular mechanics simulation (see figure).
