0D organic–inorganic antimony halides have attracted increasing attention due to the non-toxicity, high stability, and superior photoluminescence quantum yield (PLQY). Here, a series of hybrid antimony chlorides with the same organic cation ethyltriphenylphosphonium (PhEtP), including non-emissive (PhEtP)SbCl and nine (PhEtP)SbCl-based emissive compounds, are synthesized and characterized. These emissive compounds are namely, the guest-free (PhEtP)SbCl and (PhEtP)SbCl·guest (guest = glycol, acetic acid, methanol, ethanol, n-propanol, i-propanol, acetone, and acetonitrile). The solvent used can alter the coordination mode of Sb because the solvation effect affects the reactivity of the anions ([SbCl] and Cl), leading to the formation of either ASbCl or ASbCl. The solvents can be even incorporated into the crystal structure, where stronger interaction with [SbCl] leads to higher temperature of the escape of the solvent. The guest molecules could increase the structural rigidity of [SbCl] via hydrogen bonding and dipole–dipole interactions, which tends to reduce the room-temperature photoluminescence (PL) Stokes shift and temperature-dependent PL shift by decreasing the [SbCl] deformability, along with enhanced PLQY from 81% in guest-free to near-unity in (PhEtP)SbCl·glycol. This work shows that targeted synthesis and diversified choices of solvents provide an efficient tool to generate steady variations in hybrid emissive materials for optoelectronics.
