Abstract

Abstract : A series of inorganic–organic hybrid cadmium borates with novel [Cd@B14 O20 (OH)6 ] 2+ clusters have been synthesized, and their optical properties have also been investigated. Abstract : Four novel inorganic–organic hybrid cadmium borates, namely [EAH]2 {(py)2 Cd@[B14 O20 −(OH)6 ]} (1, py = pyridine, EA = ethylamine), [PAH]2 {(py)2 Cd@[B14 O20 (OH)6 ]} (2, PA = propylamine), [pyH]2 {(py)2 Cd@[B14 O20 (OH)6 ]} (3 ) and {(AImH)2 Cd@[B14 O20 (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@B14 O20 (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.
