Abstract Zero‐dimensional (0D) organic metal halides (OIMHs) with room‐temperature phosphorescent (RTP) properties have aroused great research enthusiasm due to their long lifetime of triplet excitons and environment stability. Despite extensive on the RTP emission OIMHs in different ions, there has been limited reporting excellent luminescent originating from ligands via metallic halide modulation, although they intriguing properties. Here, piperonylamine (piperA) is taken as cations two new are synthesized, 3 ClSbCl 5 ClInCl ·H 2 O, differently enhanced compared (piperA)Cl ligand. Structural photophysical studies reveal that increased π–π stackings between adjacent piperA O. Mechanism analysis demonstrates diverse stacking arrangements crystal structure result distinct energy transfer pathways, potentially accounting for varying degrees enhancement lifetime. This work developed a method regulating OIMH using ions achieve emission, providing approach designing ultra‐long materials.

Organic–inorganic metal halides (OIMHs) exhibiting superior optoelectronic properties have shown broad applications in sensing, photovoltaic devices, information storage, and biological imaging. Compared with pure inorganic or organic materials, OIMHs are distinguished by their hybrid feature, processability of components robustness units, as well plentiful luminescent sources derived from ligands, self‐trapped excitons (STEs) lattices, the energy transfer between species. Thereinto, chemical composition tunability component, ions, halogen provides multiple adjustable sites to tailor structures physicochemical properties. However, how realizing effective tunable luminescence for desired through rational regulation has become a challenge. In this review, starting structurally OIMHs, feasible methods regulating summarized, which include change components, dimensionality configurations species, heterometal systematic multisite fine‐tuning based on specific matrix. Finally, challenges synthesize promising performance discussed.
