Recently,fluorescence chemosensors have attracted great interest in the field of coordination polymers because of their potential in the application of environment detection,such as pollutant,heavy metals and so on.[1,2] One of the most challenging but promising synthetic strategies to achieve such multifunctionalized materials is the simultaneous assembly of metal ions and small organic ligands under hydro(solvo)thermal condition,resulting in unpredictable final products,which could also be ascribed as an in-situ synthetic approach.[3]Through this synthetic strategy,new coordination polymers that are inaccessible or not easily formed under conventional conditions may be easily obtained in high yield.
