Dr. Rafel Prohens and Anna Protell, members of the Polymorphism and calorimetry Technology, have published the article “Single-Stranded Molecular Helical Assembly from a Self-Complementary Squaramide Compound” at the review Crystal Growth & Design, which belongs to the American Chemical Society and is the review of Crystal Engineering with the highest impact index (4689). The abstract of the article: "A new helical crystal structure of a disquaramide compound has been solved by means of direct methods from powder X-ray diffraction data. It contains a racemic mixture of alternating clock/anticlock wise rotating helices which are formed through an unprecedented combination of strong squaramide−squaramide and amine−phenol interactions, both in a head-to-tail fashion”. |
