Twisted pyrene with perfect hetero atomic cavity optical sensor for Hg22+ and Pb2+

A pyrene-induced PET-based chemosensor for biologically important Zn(ii) ions: application in test strips and live cell imaging studies

“…Generally, pyrene scaffolds display ve distinct, well-dened absorption bands between 215 and 350 nm. 32,33 Based on the above discussion, in the present work, we synthesized a new potent sensor DTQ with a pyrene backbone for quick detection of Zn(II) using a uorescence turn-on mechanism with excellent selectivity and sensitivity. The DTQ showed nanomolar detection of Zn(II).…”
