A muconic acid derivative isomeric organic–inorganic metal halide with high-temperature phase transition

Abstract

(Z,Z)- and (E,E)-[BPHD]ZnCl4 are the first muconic acid derivative organic–inorganic metal halides, in which the EE-isomer exhibits a high phase transition temperature of up to 449.4 K.

Successive high-temperature phase transitions triggered dielectric switching in a one-dimensional hybrid perovskite with blue emission

“…Exploration for materials with high-temperature phase transition is critical for advancing the field of hybrid perovskites, which has a direct bearing on the effectiveness of the material in harsh working conditions and holds great promise for applications in electronic and optoelectronic devices, particularly in the realm of switches and memories. 21–23 Despite the extensive array of efforts directed towards manipulating phase transition temperatures through strategies such as halogen substitution, modulation of intermolecular interactions, and engineering of void occupancy, 24–28 reports on hybrid perovskite phase transition materials that capitalize on the synergistic effects of symmetry breaking and unconventional configuration changes are notably scarce. In recent studies focused on phase transition hybrid crystals, it has been discovered that certain organic cations with adaptable cis / trans -configurations can serve as unique components.…”
