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.

Triphenylene derivatives: chemosensors for sensitive detection of nitroaromatic explosives.

New triphenylene derivatives 3 and 5, synthesized using a Suzuki-Miyaura coupling protocol and by a click reaction respectively, serve as potent chemosensors for various electron deficient nitroaromatic explosives, such as picric acid, trinitrotoluene, dinitrotoluene and dinitrobenzene. Derivative 5 exhibits a more sensitive response towards the nitroaromatics compared to derivative 3 due to its ordered organization. Furthermore, the solution coated strips of derivative 3 and gel coated strips of derivative 5 can detect picric acid in the range of 14 pg cm(-2), thus providing a simple and low cost method for the detection of picric acid in aqueous solution and in a contact mode.

A triphenylene based zinc ensemble as an oxidation inhibitor.

The zinc complex of a new triphenylene based receptor is evaluated for its anti-oxidant activity which is better in comparison to that of commercially available anti-oxidants.
