Aggregates of a triphenylene based chemosensing ensemble for sensitive detection of cyanide ions in an aqueous medium.

Nanoaggregates of a supramolecular ensemble of triphenylene derivative 3 and Cu(2+) ions exhibit 'turn-on' response towards CN(-) ions in an aqueous medium and can detect the trace amount of inorganic cyanide ions (NaCN) in tap water and blood serum milieu.
