Cover Picture: Dipyrrolyl-Functionalized Bipyridine-Based Anion Receptors for Emission-Based Selective Detection of Dihydrogen Phosphate (Chem. Eur. J. 5/2007)

The extremely rare (and obviously apocryphal) Big Mouth Pyrrole Anglerfish that fluoresces in its hungry state until it is well fed with phosphate anion is depicted on the cover. This cover image was produced by the authors using an image purchased with associated rights from Image Quest Marine (www.imagequestmarine.com). In their Full paper on page 1374 ff., J. L. Sessler et al. discuss the selectivity of a new pyrrole‐based receptor for phosphate ions.
