Room‐Temperature Helix‐to‐Disc Conversion of Thia[6]helicene S,S‐Dioxides to Coronene via In Situ Phenoxide Anion Generation

Chemistry – A European Journal, EarlyView.
In situ phenoxide formation at the benzene terminus triggers room‐temperature conversion of thia[6]helicene S,S‐dioxides to coronene. The solubility contrast drives product precipitation, enabling isolation by simple filtration. This pericyclic annulation between the helical termini provides direct access to coronene‐type planar architectures ...

Variable Temperature Studies of Two Calcium Uranates α‐Ca3UO6 and Ca2UO5

Chemistry – A European Journal, EarlyView.
The structures and thermal responses of the calcium uranates α‐Ca3UO6 and Ca2UO5 were investigated using in situ synchrotron x‐ray diffraction and neutron powder diffraction. Despite the very similar chemical compositions, the structural response of the two calcium uranates is shown to be complex and varied.

Click Capture SELEX for the Identification of Click‐Modified Aptamers Targeting Small Molecules in Solution

Chemistry – A European Journal, EarlyView.
Using kanamycin A as a model target, we developed click‐capture SELEX to identify nucleobase‐modified aptamers capable of binding small molecules in solution. This approach enables flexible incorporation of nucleobase modifications via CuAAC, allowing the chemical properties of the aptamer to be tailored to the target molecule.
