Resembling a bundle of cereal stalks, this atomic force microscopy (AFM) image depicts the first ionic organic nanocrystals to have a sheaf-like structure. Ursula Mazur, of Washington State University, US, and colleagues grew the π-conjugated molecules from two electroactive porphyrin synthons: tetra(4-aminophenyl)porphyrin and tetra(4-sulfonatophenyl)porphyrin. These building blocks assembled themselves into branched structures – the higher the reaction temperature the longer and more numerous their branches.
