A new lanthanide coordination polymer (LnCPs) of {[Tb₂(4-BMBA)₆(H₂O)₄]•(4,4′-bpy)}_n (TbCPs, 4-BMBA = 4‑bromo-3-methylbenzoic acid, 4,4′-bpy = 4,4′-bpy) was obtained successfully by the introduction of 4-BMBA. The optical properties of TbCPs are studied, and in the subsequent sensing experiments, it is found the TbCPs is a highly selective sensor for Ca²⁺, and it shows excellent electrochemical property.
