A series of tris( β ‐diketonato)lanthanides with Yb 3+ , Eu 3+ , and Nd 3+ centers were characterized as luminescent sensing probes specific to glutamic acid, aspartic acid, and their dipeptides, which are important substrates involved in nervous systems, taste receptors, and other biological systems. In particular, tris(6,6,7,7,8,8,8‐heptafluoro‐2,2‐dimethyloctane‐3,5‐dionato)ytterbium(III) exhibited a near‐infrared emission around 980 nm in response to these biological substrates. Near‐infrared‐emissive complexes have several advantages over common luminescent probes; therefore, the proposed lanthanide complexes have potential analytical applications in proteomics, metabolics, food science, astrobiology, and related technologies.
