A Semiconducting Organic-Inorganic Hybrid Metal Halide with Switchable Dielectric and High Phase Transition Temperature

Organic-inorganic hybrid metal halides with temperature-triggered responsive switchable dielectric properties have evoked great attention for their potential application in the field of optoelectronic information. Here, we present a new organic-inorganic hybrid metal halide switchable dielectric material, [(C3H5)(2)N(CH3)(2)](2)SnCl6 (1), which is obtained by the reaction of diallyldimethylaminium chloride and tin(IV) chloride pentahydrate. Compound 1 exhibits excellent high-temperature switchable dielectric performance and antifatigue. Notably, 1 also exhibits multifunctionality with semiconducting and photoluminescence property. Such a Sn(IV)-based organic-inorganic hybrid with outstanding switchable dielectric, semiconducting, and photoluminescence characteristics will pave a new approach in the development of Sn(IV)-based metal halides with practical applications.
