Abstract

Hybrid organic–inorganic antimony halides have attracted increasing attention due to the non‐toxicity, stability, and high photoluminescence quantum yield (PLQY). To shed light on the structural factors that contribute to the high PLQY, five pairs of antimony halides with general formula A2SbCl5 and A2Sb2Cl8 are synthesized via two distinct methods and characterized. The A2SbCl5 type adopts square pyramidal [SbCl5] geometry with near‐unity PLQY, while the A2Sb2Cl8 adopts seesaw dimmer [Sb2Cl8] geometry with PLQY≈0 %. Through combined data analysis with the literature, we have found that A2SbCl5 series with square pyramidal geometry generally has much longer Sb⋅⋅⋅Sb distances, leading to more expressed lone pairs of SbIII. Additional factors including Sb−Cl distance and stability of antimony chlorides may also affect PLQY. Our targeted synthesis and correlated insights provide efficient tools to precisely form highly emissive materials for optoelectronic applications. [ABSTRACT FROM AUTHOR]
