title: A reversible fluorescent Hg2+/K+ switch that works as keypad lock in the presence of F- ion.
abstract: A thiacalix[4]arene based fluorescent chemosensor 3 of 1,3-alternate conformation bearing two dansyl groups and a crown-5 ring behaves as an "On-Off" reversible switch for two chemical inputs Hg(2+) and K(+) ions and mimics a molecular level keypad lock in the presence of F(-) ions.
