Abstract. Halogenation, generally introduced on aromatic amino acids, is becoming a key supramolecular tool in peptides. Herein, we report the crystal structures and DFT study of two bis-halogenated tyrosines showing the subtle relationship between hydrogen and halogen bonds in promoting their supramolecular self-assembly.

The SupraBioNano resreach group is glad to announce its 1^st School of Supramolecular and Bio-Nanomaterials!

The field of supramolecular systems and bio-nanomaterials is both timely and highly interdisciplinary and this School wishes to foster a collaborative, multidisciplinary, and dynamic “playground” for presenting and discussing the most recent research results in field of supramolecular chemistry and self-assembled materials.

This School aims to provide a research-led overview of the current state-of-the-art in self-assembly phenomena, applied supramolecular chemistry, and bio-nanomaterials. Taking inspiration from Nature, the attendees will be guided through all aspects of chemistry underpinning the formation of hierarchical structures and complex functionalities.

The School is designed for PhD students, Post-Docs, and young scientists with various fields of interest, who aim at mastering the phenomena associated with molecular recognition and self-assembly, and the design and preparation of functional molecules and materials for a wide-range of high-end applications. During an intense training week the attendees will learn how to design and develop functional materials through the combination and assembly of organic, inorganic, coordination, biological molecules, and higher-level building units.

Welcome to the 1^stSchool

Dr. Claudia Pigliacelli, Prof. Valentina Dichiarante, Prof. Francesca Baldelli Bombelli, Prof. Pierangelo Metrangolo, Prof. Giancarlo Terraneo and others have recently published an article on Nature Communications about "High-resolution crystal structure of a 20 kDa superfluorinated gold nanocluster".

The full paper can be found at the following link: High-resolution crystal structure of a 20 kDa superfluorinated gold nanocluster.

Abstract. Crystallization of atomically precise nanoclusters is gaining increasing attention, due to the opportunity of elucidating both intracluster and intercluster packing modes, and exploiting the functionality of the resulting highly pure crystallized materials. Herein, we report the design and single-crystal X-ray structure of a superfluorinated 20 kDa gold nanocluster, with an Au₂₅ core coated by a shell of multi-branched highly fluorinated thiols (SF₂₇) resulting in almost 500 fluorine atoms, i.e., ([Au₂₅(SF₂₇)₁₈]⁰). The cluster shows a switchable solubility in the fluorous phase. X-ray analysis and computational studies reveal the key role of both intracluster and intercluster F···F contacts in driving [Au₂₅(SF₂₇)₁₈]⁰ crystal packing and stabilization, highlighting the ability of multi-branched fluorinated thiols to endow atomically precise nanoclusters with remarkable crystallogenic behavior.
