Article Abstract

Interestingly, neutral tetrathia[22]porphyrin(2.1.2.1) (TTP) acts as an efficient chemosensor for the detection of Hg 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 Hg ions, which is suggestive of metal induced macrocyclic self-assembly and is further substantiated by the SEM, TEM and particle size measurement studies.
