Abstract:

Lanthanide coordination polymers have been widely investigated in fluorescent sensing owing to their characters in component, structure, and properties. However, the functional targeted construction of lanthanide coordination polymers is still a challenge. Herein, we report the construction, characterization, and properties investigation of a new Tb3+ coordination polymer, namely [Tb(TZI)(DMF)2(H2O)]·(H2O)(1)(H3TZI=5-(1H-tetrazol-5-yl)isophthalic acid and DMF=N,N-dimethylmethanamide). Utilizing the distinct affinities between Tb3+ ion and carboxylate/tetrazole groups, the construction of coordination polymer is well achieved, while the tetrazole group has been introduced into the framework of coordination polymer as sensing sites. As a result, complex 1 reveals ions dependent emissions enhancement owing to the coordination between the ions and the tetrazole sites, which could be utilized for the sensing of Zn2+ and Na+ ions. These results could be instructive for the fluorescent sensing function targeted construction of lanthanide coordination polymers.

Key words: coordination polymer, lanthanide metals, construction, fluorescent sensing
