Enlarging the ring by incorporating a phosphonate coligand: from the cyclic hexanuclear to octanuclear dysprosium clusters
Solvothermal reaction of a double pyrazinyl hydrazone ligand EDDC(2-) with Dy(OAc)3 results in a cyclic hexanuclear cluster [Dy6(EDDC)2(OAc)14(H2O)2]·MeOH·2H2O (). The addition of 1-naphthylphosphonate to the reaction mixture expands the ring size with the formation of a cyclic octanuclear cluster [Dy8(EDDC)4(O3PC10H7…
One-step DGC assembly and structural characterization of a hairy particle zeolite-like organic–inorganic hybrid as an efficient modifiable catalytic material
Organic-inorganic hybrid microporous crystalline molecular sieves, extending the application of conventional zeolites in the fields of selective catalysis and adsorption, have aroused great interest in chemists. However, the complicated and difficult synthesis of organic-inorganic hybrid microporous molecular sieves b…

Hybrid ionic dendrimers prepared <italic>via</italic> ionic self-assembly by grafting of a cationic PPI dendrimer with bifunctional electroactive carbazole dendrons, display photoluminescence properties and self-assembly into nematic, smectic or columnar mesophases.
An electrochemistry assisted approach for fast, low-cost and gram-scale synthesis of mesoporous silica nanoparticles
Gram-scale mesoporous silica nanoparticles (MSNs) were prepared by a facile electrochemistry assisted sol–gel approach.
Binding or aggregation? Hazards of interpretation in studies of molecular recognition by porphyrins in water
Reports have suggested that polar porphyrins such as tetraphenylporphine tetrasulfonate (TPPS) can serve as carbohydrate receptors in water. Here we find that TPPS shows changes in UV-visible absorption when treated with glucose, but that these are best explained by altered aggregation states and not by formation of a…

Quantum-trajectory Monte Carlo method for study of electron–crystal interaction in STEM
In this paper, a novel quantum-trajectory Monte Carlo simulation method is developed to study electron beam interaction with a crystalline solid for application to electron microscopy and spectroscopy. The method combines the Bohmian quantum trajectory method, which treats electron elastic scattering and diffraction i…
Probing the structural changes accompanying a spin crossover transition in a chiral [Fe( ii )(N 3 O 2 )(CN) 2 ] macrocycle by X-ray crystallography
The preparation and characterization of a novel chiral macrocycle S,S-[FeII(PhCH2OCH2)2(N3O2)(CN)2] (4) is presented. Magnetic susceptibility studies reveal that this complex undergoes a gradual spin crossover in the solid state with no thermal hysteresis. Variable temperature X-ray diffraction studies on single cryst…
