thermal- and light-induced spin transitions, yet losing the cooperativity. Finally, SCO/2D horizontal hybrid devices based on CVD-graphene are produced using these films. Being the first ones of this type utilizing molecules of the Fe[H2B(pz)2]2(L)} family, with L = tzpy and btz, the devices have allowed the successful detection of the thermal SCO transition through the electric properties of CVD-graphene
在不同类型的可转换分子化合物中,可升华的 Fe( II ) SCO 分子为开发响应外部刺激的智能设备提供了合适的平台。在此,我们报道了属于 Fe[H 2 B(pz) 2 ] 2 (L)} 家族的三种新型中性 Fe( II ) SCO 分子的合成、晶体结构和磁性,具有双齿-α-二亚胺配体 L = 3-(pyridin-2-yl)-[1,2,3]triazolo[1,5- a ]pyridine (tzpy), 5,5',6,6'-tetrahydro-4 H ,4' H - 2,2'-双(1,3-噻嗪) (btz) 和 4,4',5,5'-四氢-2,2'-联噻唑 (bt) ( 1 , 2和3,分别),以及1和3的两种溶剂化形式。所有三种去溶剂化化合物都呈现出具有不同程度的协同性和有效性的热诱导和光诱导的 SCO 跃迁。此外,1和2被证明在 HV 条件下可升华,提供 200 nm 厚的均匀薄
