reports on muconic acid derivative OIMHs with phase transitions. In this work, we successfully synthesized the first muconic acid derivative OIMHs (Z,Z)- and (E,E)-[BPHD]ZnCl4 (BPHD = N1,N6-bis(piperidine-1-yl) hexa-2,4-diene diamide). Both of them crystallized in the monoclinic space group P21/c at room temperature. Notably, (Z,Z)-[BPHD]ZnCl4 does not exhibit phase transition behavior, while (E,E)-[BPHD]ZnCl4
有机-无机金属卤化物(OIMHs)由于其多样化的物理特性,如光电特性、光致发光、磁性和铁电性,在近几十年来引起了极大的关注。除了这些令人着迷的物理特性之外,OIMH 的相变也引起了人们的广泛兴趣。由于存在顺式、顺式 ( Z , Z ) 和反式、反式 ( E , E ) 异构体,粘康酸引起了广泛的关注。然而,目前尚未见关于粘康酸衍生物OIMHs具有相变的报道。在本工作中,我们成功合成了第一个粘康酸衍生物OIMHs ( Z , Z )- 和( E , E )-[BPHD]ZnCl 4 (BPHD = N 1 , N 6 -bis(piperidine-1-yl) hexa-) 2,4-二烯二酰胺)。它们在室温下均以单斜晶系空间群P 2 1 / c结晶。值得注意的是,( Z , Z )-[BPHD]ZnCl 4不表现出相变行为,而( E , E )-[BPHD]ZnCl 4具有高达449.4 K的高温相变,高于大多数
