•Hexaphenylbenzene based derivatives 3 and 4 shows AIEE.•Aggregates of 3, having pyrene groups form fluorescent nanofibres in presence of Hg2+.•3-Hg2+ and 4-Hg2+ exhibit sensitive and selective response towards PA.•3-Hg2+ ensemble can detect picric acid in the range of 2.29 fg/cm2.•3-Hg2+ coated TLC strip detect picric acid in contact mode.
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 2.29 fg/cm2, thus, providing a simple, portable and low cost method for detection of picric acid in solution and in contact mode.
