biostudies-literatureUnknown11(4)Li YThe luminescence of dielectric phase transition materials is one important property for technological applications, such as low-energy electron excitation. The combination of dielectric phase transitions and luminescence within organic-inorganic hybrids would lead to a new type of luminescent dielectric phase transition multifunctional material. Here, we report two novel A₂BX₄ organic-inorganic hybrid complexes [Me₃NVinyl]₂[MnCl₄] 1 and [Me₃NVinyl]₂[MnBr₄] 2, ([Me₃NVinyl] = trimethylvinyl ammonium cation). The complexes 1 and 2 were found to undergo continuous reversible phase transitions as well as switch dielectric phase transitions. Strikingly, intensive red luminescence and green luminescRSC advances2329-2336https://www.ebi.ac.uk/biostudies/studies/S-EPMC8693754biostudies-literatureRed/green-light emission in continuous dielectric phase transition materials: [Me₃NVinyl]₂[MnX₄] (X = Cl, Br).PMC8693754Li HLi YYang JJiang TLin LQian KfalseRed/green-light emission in continuous dielectric phase transition materials: [Me₃NVinyl]₂[MnX₄] (X = Cl, Br).The luminescence of dielectric phase transition materials is one important property for technological applications, such as low-energy electron excitation.
