Abstract

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.
