摘要：

A three-dimensional uranyl phosphonate framework [BTA][(UO2)3(TppmH)(H2O)3]center dot 0.75H2O (UPF-109) (Tppm = tetrakis[4-(dihyroxyphosphoryl)phenyl]methane, BTA = benzyltriethylammonium chloride) has been synthesized using the hydrothermal method. The structure of UPF-109 shows that dimers and monomers are connected to give a two-dimensional layer, and Tppm ligands link the layers to give a 3D structure with two types of channels. To provide more detailed information, PXRD, TG, IR, UV-vis, and photoluminescence were performed. In addition, the relation between fluorescence intensity and temper-ature demonstrates the potential application of UPF-109 in fluorescence temperature sensors. (c) 2022 Elsevier B.V.
