Selective luminescence chemosensing of potassium ions based on a novel platinum(II) alkynylcalix[4]crown-5 complex

A novel dinuclearplatinum(H) alkynylcalix[4]crown5 complex has been demonstrated to show luminescence enhancement upon metal ion-binding, with a more selective binding toward K+ over the other alkali-metal and alkalineearth-metal ions. © 2006 American Chemical Society.link_to_subscribed_fulltex
