1,2‐Dihydroxyanthraquinone, 6,7‐Dihydroxyisobenzofuranone and 7,8‐Dihydroxyquinolinone Derivatives as Ligands for the Self‐Assembly of Hierarchically Formed Lithium‐Bridged Titanium(IV) Helicates

European Journal of Organic Chemistry, EarlyView.
Catechol‐based annulated aromatics with carbonyl units are ideal ligands for the formation of titanium(IV) containing lithium‐bridged hierarchical helicates. They allow for the first time the use of amide units to obtain the dimeric helicate‐type complexes.

Revealing Structure–Property Coupling During Thermal Conversion of Metal–Organic Frameworks

Small, EarlyView.
Multifrequency atomic force microscopy (AFM) combined with hybrid density functional theory (DFT) and complementary spectroscopic techniques uncovers transient nanoscale states during Cu‐BTC MOF conversion. Intermediate Cu2O/CuO‐carbon nanocomposites maximize mechanical robustness and functionality, while fully oxidized porous CuO enhances light ...
