title: Torsionally restricted tetradentate fluorophore: a swivelling ligand platform for ratiometric sensing of metal ions.
abstract: A conformationally pre-organized ligand platform allows for restricted swivelling motions of two aryleneethynylene-appended 2,2'-bipyridyl units that function as a tight bischelator as well as a ratiometric fluorescence sensor for selected metal ions.
