Two new isostructural lanthanide metal‐organic frameworks were synthesized using lanthanide oxides and 3,3,4,4‐benzophenonetetracarboxylic acid (H 4 BPTC), namely, [ Ln (BPTC)(H 2 O) 2.5 ] [ Ln = Eu ( 1 ), Gd ( 2 )] under hydrothermal conditions. 1 and 2 revealed porous three‐dimensional structures, possessing a binodal 4, 8‐connected flu network defined by dinuclear building units. 1 and 2 were characterized by powder X‐ray diffraction (PXRD), thermogravimetric analysis (TG), infrared radiation (IR), and photoluminescence (PL) spectra. Furthermore, 1 exhibits red‐light emission under UV light irradiation and the sharp light can be easily observed by naked eyes.
