摘要：
A new two dimensional (2D) Eu3+ coordination polymer, named [Eu(BTB)(H2O)(2 center dot)solvent](n) (1) (H-3 BTB = 4,4',4 ''-benzene-1,3,5-triyl-tribenzoic acid) has been constructed and investigated for sensing properties. Complex 1 shows structural flexibility originating from the 2D layer architecture, which could be triggered by the removal/restore of coordinated and guest solvent molecules. Benefiting from the high stability and intensive Eu3+ based emission of 1, it could be used as an effective fluorescence sensor for acetone with remarkable anti-interference and recyclability. In addition, the impact of structural features on the sensing performance of the complex was investigated, and enhanced sensing sensitivity was achieved with the desolvated complex.
