A peptide topological template for the dispersion of [60]fullerene in water [PDF]

open access: yes, 2015
Solubilization of [60]fullerene in water is a major challenge for biological and medical applications. To this purpose in this communication we describe for the first time a new dispersing system based on a peptide topological template.

Poly(thioether) vitrimers via transalkylation of trialkylsulfonium salts [PDF]

open access: yes, 2017
Vitrimers are permanently cross-linked organic polymers that can be reshaped, molded, and recycled without loss of network integrity. Herein, we report poly(thioether) networks, prepared through a straightforward thiol-ene photopolymerization, that can ...

Aromatic‐Carbonyl Interactions as an Emerging Type of Non‐Covalent Interactions

open access: yesAdvanced Science
Aromatic‐carbonyl (Ar···C═O) interactions, attractive interactions between the arene plane and the carbon atom of carbonyl, are in the infancy as one type of new supramolecular bonding forces.

Carbazole-based biradicaloids as potential building blocks for dynamic covalent chemistry [PDF]

open access: yes, 2018
Pi-conjugated biradical compounds become essential building blocks in DCC (dynamic covalent chemistry).1 This field is based on the creation of structural scaffolds based on chemical components which interact through strong but reversible bonds ...

NaI revisited: Theoretical investigation of predissociation via ultrafast XUV transient absorption spectroscopy. [PDF]

open access: yes, 2019
Avoided crossings can trigger abrupt changes of electronic character and redirect the outcomes of photochemical reactions. Here, we report a theoretical investigation into core-level spectroscopic probing of predissociation dynamics of sodium iodide (NaI)
