N2 - New luminescent Ln-MOFs, [Ln2(d-cam)(Himdc)2(H2O)2] (Ln = Eu 1, Tb 2, d-H2cam = d-camphoric acid, H3imdc = 4,5-imidazole dicarboxylic acid) have been synthesized via hydro(solvo)thermal reactions. X-ray single crystal structure analysis reveals that they are isomorphic and both crystallize in the orthorhombic space group Pna21. Compound 1 shows good chemical resistance to both acidity and alkalinity solutions with pH ranging from 2 to 13 and is highly stable in several boiling solvents, which make it potentially useful for wide-range pH sensors, especially in the physiological environment with pH = 6.8-8.0. Careful adjusting of the codoping ratio of Eu3+/Tb3+ into the same framework of 1 affords a mixed Ln-MOF, formulated as [Eu0.7Tb0.3(d-cam)(Himdc)2(H2O)2]3, which has demonstrated to be a viable probe for sensing temperature in a wide temperature range from 100 to 450 K.
