The cover picture shows an isoguanosine hydrogel formed by self‐assembly that consists of interconnected helical fibers. Gel formation is specific for distinct alkali metal ions and depends on the sugar structure and the skeleton of the nucleobase. Isoguanosine gels are stable for more than three months while guanosine gels collapse within minutes or hours. The hydrogels display excellent loading and releasing capabilities for small molecules. Details are given in the Full Paper by Frank Seela and co‐workers on page 826 in Issue 6, 2017 (DOI: 10.1002/cplu.201600586).
