A new anionic framework {[Me 2 NH 2 ] 0.125 [In 0.125 (H 2 L) 0.25 ] ⋅ x DMF} n ( 1 ) with one‐dimensional (1D) channels along the c axis of about 13.06×13.06 Å 2 , was solvothermally synthesized and well characterized. Post‐synthetic cation exchange of 1 with Eu 3+ , Tb 3+ , Dy 3+ , Sm 3+ afforded lanthanide(III)‐loaded materials, Ln 3+ @ 1 , with different luminescent behavior, indicating that compound 1 could be used as a potential luminescent probe toward different lanthanide(III) ions. Additionally, compound 1 exhibits selective adsorption ability toward cationic dyes. Moreover, the RhB@ 1 realized the probing of different organic solvent molecules by tuning the energy transfer efficiency between two different emissions, especially for sensing DMF. This work highlights the practical application of luminescent guest@MOFs as sensors, and it paves the way toward other one/multi‐color luminescent host–guest systems by rational selection of MOF hosts and guest chromophores with suitable emissive colors and energy levels.
