Cover Picture (Angew. Chem. Int. Ed. 24/1999)
The cover picture shows color and wine—both can be symbols for the Joy of living or the state of melancholy, it depends on their character and the mood of the recipient. What could be better than this composition for decorating the final issue of the old millennium? Color and wine also symbolically represent the importance of chemistry for investigating all aspects of nature and applying the knowledge gained for the good of humanity. That chemistry will continue to be fruitful in the new century is certain—let us just hope that only few bitter fruits will be harvested. Angewandte Chemie has guided chemists through the past 100 years, in the beginning as a German chemical magazine and at the end as an international scientific journal. Page through and reread some of the older issues—it's worth it. Now a few details about the cover picture: The top vial contains only an indicator, the middle vial indicator and a synthetic receptor selective for tartrate/malate, and the last vial indicator, receptor, and tartrate. The color changes can be used to quantitate the amount of tartrate/malate in grape-derived beverages including wine. Further details are provided by John J. Lavigne and Eric V. Anslyn on pages 3666 ff.
