Zero-dimensional（0D） hybrid metal halides with tunable self-trapped exciton（STE） emissions are promising for lighting and displaying applications. In particular，0D hybrid metal halides with dual-band emissions arising from singlet and triplet STEs have potentials in white-light solid-state lighting. Herein，two 0D hybrid antimony chlorides，（CHP）SbCl（Ⅰ）and（CHP）SbClHO.0. 5DMF（Ⅱ）（CHP = tetraphenylphosphonium，PhP）are reported. The compounds Ⅰ and Ⅱ exhibit single broadband red and yellow emissions upon low-energy （LE）photons（e. g. 360 nm）excitation，respectively，arising from their triplet STEs. In addition，upon high-energy（HE）photons（e. g. 310 nm）excitation，the compound Ⅱ shows a dual-band emission with an additional blue emission band deriving from singlet STEs，exhibiting a warm-white emission. Intriguingly，a reversible phase transformation between Ⅰ and Ⅱ is achieved through a dynamic insertion and extraction of DMF and water molecules. This work unravels the effect of small molecules on the crystalline structures and the conversion between single- and dual-band emission properties in 0D antimony halides，which could guide the design of 0D hybrid metal halides for sensor applications.
