摘要
在自旋交叉(SCO)材料中加入荧光特性,旨在通过自旋态转变控制荧光,从而应用于磁光开关和信息处理,这是一个极具吸引力的研究方向。在本研究中,我们制备了两种一维环状链状铁(II)配位聚合物,分别命名为[Fe(DPPC)2(NCS)2]⋅CH3OH⋅o-C6H4Cl2(1、DPPC=3,6-二-4-吡啶基-9-[4-(4-吡啶基)苯基]-9H-咔唑)和[Fe(PDPC)2(NCS)2](2,PDPC=3,6-二(吡啶-4-基)-9-苯基-9H-咔唑)。通过单晶 X 射线研究和磁性测量分析,验证了 1 在 50~200 K 温度范围内的两步 SCO 行为。
Construction of Spin Crossover-Fluorescent Bifunctional Cyclic Chain-Like Fe(II) Compounds from Carbazole Ligands
The incorporation of fluorescent properties into spin-crossover (SCO) materials, aiming at controlling fluorescence via spin-state transitions for applications in magneto-optical switching and information processing, represents an appealing research direction. In this study, we prepared two examples of one-dimensional cyclic chain-like Fe(II) coordination polymers, denoted as [Fe(DPPC)2(NCS)2]⋅CH3OH⋅o-C6H4Cl2 (1, DPPC=3,6-di-4-pyridinyl-9-[4-(4-pyridinyl)phenyl]-9H-carbazole) and [Fe(PDPC)2(NCS)2] (2, PDPC=3,6-di(pyridin-4-yl)-9-phenyl-9H-carbazole). Analyses through single-crystal X-ray studies and magnetic measurements validate the two-step SCO behavior of 1 within the temperature range of 50~200 K. Additionally, when combined with temperature-dependent fluorescence emission spectroscopy, the results demonstrate the coexistence of SCO and fluorescence in 1.
