The cover picture shows scanning electron microscopy images of organic nanowires and platelets. High-aspect- ratio nanowires were formed via synergistic hydrogen bonding and dipole–dipole interactions of a hydrogen-bonding azobenzene flavin system. In contrast, micrometer-size platelets were formed using a highly analogous non-hydrogen-bonding molecule. Co-precipitation of the two analogous molecules provides efficient control over both nanowire length and diameter. This strategy offers an opportunity to engineer supramolecularassemblies with well-defined size, shape, and morphology for electronic and optical applications.

Rotello, et al. beginning on page 2074.
