  Selective and reversible recognition of Hg2+ ions by Tetrathia[22]porphyrin(2.1.2.1)

  摘要：

  Interestingly, neutral tetrathia[22]porphyrin(2.1.2.1) (TTP) acts as an efficient chemosensor for the detection of Hg2+ ions at ppb concentration. Consequent to binding the molecular plane of TTP bends and it has been supported by the DFT calculations. A rise in levelling off tail is observed in the electronic absorption spectrum in the presence of Hg2+ ions, which is suggestive of metal induced macrocyclic self-assembly and is further substantiated by the SEM, TEM and partide size measurement studies.
