      Instead of binding two CuII ions, macrocycles with two bis(carboxamido)pyridine ligands linked by ethylene units bind only one, and feature intramolecular hydrogen bonding that influences the CuII/III redox potential. A purposefully mononucleating ligand with ortho-phenylene linkers displays a different hydrogen bonding pattern, involving carboxamido N–H interactions with solvate molecules.

      Thumbnail image of graphical abstract

      Cage-chiral P–C cage compounds are a new class of chiral ligands. A stereoselective rearrangement performed with highly enriched P5-deltacyclene enantiomers is accompanied by a unique cage inversion, which results in almost mirror-symmetric CD curves of related pairs of P5-deltacyclene/iso-P5-deltacyclene enantiomers. The absolute structure of a W(CO)5 complex enantiomer confirms the observation.

      A simple synthesis of Al2O3–TiO2 and ZnO–TiO2 mesoporous hollow composite assemblies consisting of homogeneously mixed primary particles at the nano level was accomplished. A phase transition from anatase to rutile was not observed for the Al2O3–TiO2 composite assemblies (50 % Al) even at 1000 °C. Band gap energies of the ZnO–TiO2 hollow assemblies were tuned (3.12–3.21 eV) by changing their Zn content.
