Three new isostructural 3D lanthanide metal–organic frameworks (Ln‐MOFs), {H[LnL(H 2 O)]⋅2 H 2 O} n ( 1‐Ln ) (Ln=Eu 3+ , Gd 3+ and Tb 3+ ), based on infinite lanthanide‐carboxylate chains were constructed by employing an ether‐separated 5,5′‐oxydiisophthalic acid (H 4 L) ligand under solvothermal reaction. 1‐Eu and 1‐Tb exhibit strong red and green emission, respectively, through the antenna effect, as demonstrated through a combination of calculation and experimental results. Moreover, a series of dichromatic doped 1‐Eu x Tb y MOFs were fabricated by introducing different concentrations of Eu 3+ and Tb 3+ ions, and they display an unusual variation of luminescent colors from green, yellow, orange to red. 1‐Eu with channels decorated by ether O atoms and the open metal sites displays good performance for CO 2 capture and conversion between CO 2 and epoxides into cyclic carbonates.
