摘要

The present work reports the synthesis, characterization, and crystal structure of a rare 2-D heterobimetallic Ca-Ag coordination polymer (CP) [Ca(DMF)(4)Ag-2(SCN)(4)](n) (1) (DMF = N,N-dimethylformamide). 1 is constructed by Ca metallic atoms, Ag-2 dinuclear cluster, and SCN- bridges. This Ca-Ag CP exhibits strong luminescence property in its DMF suspension, and has been exploited as a highly sensitive sensor for the detection of TNP. Moreover, the energy-transfer mechanism of 1 for sensing TNP had been preliminarily elucidated.
