Congratulations to Dr. Fang-nan Xiao's paper published on Anal. Chem. on March 30th
Self-assembly is an effective way to fabricate molecular optical materials. However, this
strategy changes usually the nanoenvironments surrounding the fluorescence molecule, yielding low luminescence efficiency. Herein, we report the intercalation of ruthenium polypyridine complex (Ru complex) into the interlayer galleries of layered double hydroxides (LDHs), forming a Ru/LDHs hybrid. The Ru complex existing as ordered monolayer state in the hybrid exhibits highly thermal and photo stability. Especially, its luminescence efficiency is increased by ca 1.7 times, lifetime is increased by ca 1 times as compared to the ones of free molecules. We constructed a Ru/LDH sensing platform based on fluorescence quenching effect for highly sensitive detection of TNT with a detection limit of 4.4 µM.
