Abstract:

Recently, optical-functional metal-organic frameworks (MOFs) have shown very attractive application prospects in different areas.1 Since that, constructing suitable MOFs to explore the excellent optical-functional material is always one interesting and noteworthy research. Comparing to thetypical modulation of centre metal ion in lanthanide-MOF (Ln-MOF) material,2 the developments of relatively various transition metal ions in this area have been hindered by the photophysical nature of d-electron (major barrier, the nonradiative d-d transition)3 or full-filled d-orbital (like Zn(II), absent metal-to-ligand charge transfer state or ligand-to-metal charge transfer state). Hence, to construct new chromophore-derived systems and explore the relationship between photophysical properties and the structures is a convenient choice to get the appropriate optical-functional materials. Since 2013, we are very interested in constructing new chromophore-derived MOFs with 2,1,3-benzothiadiazole (BTD)4 derived organic linkers and transition metal ion. Herein, several new benzothiadiazole-derived ligands and MOFs were successfully synthesized and deep photophysical research with structural analyses showed the intimate connection between structure and photophysical property, which would be beneficial for the fast development of optical-functional BTD-derived coordination polymer material.
