The back cover picture shows in the background, a schematic representation of the structure of metal–organic framework (MOF) MIL‐103 built from edge‐sharing [LnO 9 ] (Ln = Eu 3+ , Tb 3+ ) polyhedral chains connected by the tritopic linker 1,3,5‐tris(4‐carboxyphenyl)benzene. Upon UV excitation, the latter transfers energy to the metal cations, pumping up their light emission. Because the intensity ratio of the Eu 3+ 5 D 0 → 7 F 2 (most intense peak) and Tb 3+ 5 D 4 → 7 F 5 (next most intense peak) transitions is very sensitive to temperature, below 100 K, MIL‐103 nanoparticles are among the best luminescent MOF cryogenic thermometers, with a relative thermal sensitivity of 2.85 % K –1 at 14 K. Details are discussed in the article by D. Ananias, J. Rocha et al. on p. 1967 ff .
