N2 - Aggregates of hexaphenylbenzene derivatives 3, having pyrene groups form network of fluorescent nanofibres in presence of mercury ions. Further, fluorescent nanofibres of 3-Hg2+ supramolecular ensemble exhibit sensitive and pronounced response towards the picric acid. In addition, the solution coated paper strips of 3-Hg2+ supramolecular ensemble can detect picric acid in the range of 2.29fg/cm2, thus, providing a simple, portable and low cost method for detection of picric acid in solution and in contact mode.
