Davakaran Masilamani, Mariann E Lucas, George S Hammond: Fluorogenic and chromogenic three-dimensional ionophores as selective reagents for detecting ions in biological fluids. Allied Signal, D L Webster, G H Fuchs, R C Stewart II, November 10, 1992: US05162525 (123 worldwide citation)

Novel fluorogenic and chromogenic three-dimensional ionophores are provided which selectively bond ions such as potassium, sodium, and lithium, even in neutral aqueous or alcohol media. The novel ionophores comprse an "ion-recognizing system" fused to a "signal-moiety" through one or more heteroatom ...

Divakaran Masilamani, Mariann E Lucas, George S Hammond: Ion selective fluorogenic reagents. Allied Signal, D L Webster, G H Fuchs, R C Stewart II, August 4, 1992: US05136033 (14 worldwide citation)

Novel fluorogenic ionophores have been synthesized which selectively bind ions such as potassium and sodium, even in neutral aqueous and alcoholic media and respond to such binding by fluorescence quenching or enhancement. These ionophores are ideal for the selective and direct determination of ions ...
