A novel organic-inorganic hybrid perovskite crystal, [ClC6H4(CH2)2NH3]2CuBr4 (1), having experienced an invertible high-temperature phase transition near Tc (Curie temperature Tc = 355 K), has been successfully synthesized. The phase-transition characteristics for compound 1 are thoroughly revealed by sp. heat capacity (Cp), DTA, and differential scanning calorimetry tests, possessing 16 K broad thermal hysteresis. Multiple-temperature powder X-ray diffraction anal. further proves the phase-transition behavior of compound 1. Moreover, compound 1 exhibits a significant steplike dielec. response near Tc, revealing that it can be deemed to be a promising dielec. switching material. The variable-temperature fluorescence experiments show distinct photoluminescence (PL) changes of compound 1. Further investigation and calculation disclose that the fluorescence lifetime of compound 1 can reach as long as 55.46 μs, indicating that it can be a potential PL material. All of these researches contribute a substitutable avenue in the design and construction of neoteric phase-transition compounds combining high Curie temperature and PL properties. In the experiment, the researchers used Cupric bromide(cas: 7789-45-9HPLC of Formula: 7789-45-9)
Some reported applications of Cupric bromide(cas: 7789-45-9) are: catalyst in cross coupling reactions; co-catalyst in Sonogashira coupling; lewis acid in enantioselective addition of alkynes.HPLC of Formula: 7789-45-9
