Ligand Design for Selective Complexation of Metal Ions in Aqueous Solution.

摘要

The subject matter covered by this paper is effectively described by the following table of contents: The Selection of Donar Atoms; The Neutral Oxygen Donar Atom; The Negatively Charged Oxygen Donor; The Neutral Saturated Nitrogen Donor; Unsaturated Nitrogen Donors; The Heavier Donor Atoms P, As, S and Se; Dual Basicity Scale Equations as an Aid in Selecting Donor Atoms; Chelating Ligands; The Size of the Chelate Ring and the Size of the Metal Ion; The Metal Ion Selectivity of Macrocyclic Ligands; Macrocyclic Ligands with Pendent Donor Groups; More Highly Preorganized Ligands: Cryptands, Spherands, and Other More Rigid Ligands; The Analysis of Steric Effects Efficiency; The Use of Sterically Crowding Groups to Improve Selectivity; The Effect of Restricted Rotation of the Ligand on Complex Stability; Specific complexation of larger metal ions such as Ca(II) and Pb(II); and Ligands for complexing more highly charged metal ions such as Al(III), In(III), Ga(III), or Fe(III).
