Abstract [en]

Four novel inorganic-organic hybrid cadmium borates, namely [EAH](2){(py)(2)Cd@[B14O20-(OH)(6)]} (1, py = pyridine, EA = ethylamine), [PAH](2){(py)(2)Cd@[B14O20(OH)(6)]} (2, PA = propylamine), [pyH](2){(py)(2)Cd@ [B14O20(OH)(6)]} (3) and {(AImH)(2)Cd@[B14O20(OH)(6)]} (4, AIm = 1-(3-aminopropyl) imidazole) have been solvothermally synthesized and characterized by elemental analysis, thermogravimetric analysis, IR spectroscopy, UV-Vis-NIR spectroscopy, fluorescence spectroscopy, powder X-ray diffraction, and single-crystal X-ray diffraction, respectively. They represent the first hybrid cadmium borates that exhibit 3D supramolecular open-frameworks with different topologies. All the networks are formed by the unprecedented Cd-centred cluster [Cd@B14O20(OH)(6)](2-), and further link each other via a multipoint H-bond system. UV-Vis-NIR spectral investigation reveals that these borates are wide-band-gap semiconductors. Moreover, they display strong fluorescence emission around 430 nm, making them excellent candidates for optoelectronic applications as blue materials.
