摘要

A zinc-based anionic metal–organic framework, [HDMA] _(2) [Zn _(2) (BDC) _(3) (DMA)]·6DMF (HDMA ~(+) : dimethylammonium, BDC ~(2?) : 1,4-benzenedicarboxilate, DMA: dimethylamine and DMF: N , N ′-dimethylformamide) has been solvothermally synthesized. And its cations, HDMA ~(+) , are exchanged by various lanthanides to form the hybrid systems via a post-synthetic process. These lanthanide( III )-loaded materials have shown different luminescent behaviors, indicating that this kind of anionic MOF could effectively sensitive lanthanides and be used as a potential luminescent probe towards different lanthanide ions. Besides, this system exhibits selective adsorption ability to cationic dyes, such as Rhodamine B, Basic Red 2 and Methylene Blue. RhB@ 1 has a fastest selection and realizes the probing of various organic solvent molecules as well as volatile organic benzenes (VOBs), especially for sensing acetone and aniline.
