Hybrid metal halides with tunable photoluminescence (PL) properties have emerged as a novel light-emitting material. Hybrid manganese halides are especially attractive due to the eco-friendly and highly emissive advantages. However, the PL tunability induced by structural modulation in manganese halides has rarely been investigated. Herein, a new one-dimensional (1D) hybrid manganese chloride, (4AMP)4ClMn3Cl13·HCl (4AMP = 4-(aminomethyl)pyridinium), where the corner-sharing octahedral manganese chloride chains of [Mn3Cl137-]∞ are surrounded by organic cations, has been prepared. The addition of Zn2+ ions into precursor solution results in the formation of zero-dimensional (0D) single crystals of (4AMP)Zn1-xMnxCl4·H2O (x = 0-1) with isolated [Zn1-xMnxCl42-] tetrahedral geometry. This structural transformation leads to the PL conversion from red to green emission with an increase of photoluminescence quantum yield (PLQY) from 4.9% to 12.7%. Moreover, the incorporation of other transition metal ions (e.g., Zn2+, Co2+, and Cu2+) reveals the concentration-dependent structure modulation, where the 1D to 0D structure transformations are achieved upon the introduction of these transition metal ions at high concentrations. This work provides a new strategy to modulate the structure and luminescence in manganese halides with tunable PL properties, which could be expanded to other hybrid metal halides.
