Anions play numerous indispensable roles in biological and chemical processes, as well as contributing significantly to environmental pollution. For instance, the majority of enzyme substrates and co-factors are anionic1, as is DNA itself Excess amounts of anionic pollutants such as phosphate and nitrate lead to eutrophication and consequent disruption of aquatic life cycles2. Radioactive pertechnetate from the nuclear fuel cycle may also contribute to poUution3. Given their importance, there has obviously been much effort expended in the design of anion complexing reagents, particularly over the last two decades. |
