A luminescent barium-based metal-organic framework: Synthesis, structure and efficient detection of 4-nitrobenzoic acid

A barium-based 3D luminescent MOF [Ba2(adda)2(H2adda)(H2O)2]n1 (H2adda = (2E,2′E)-3,3′-(anthracene-9,10-diyl) diacrylic acid) was successfully obtained under the solvothermal condition and structurally characterized. Compound 1 displays an unprecedented “turn-on” luminescence response toward 4-NBA and acts as a promising 4-NBA detector.206
