Multifunctional micro- and nanosized metal–organic frameworks assembled from bisphosphonates and lanthanides Abstract Phase-pure and highly crystalline [Ln(Hpmd)(H2O)] materials [where Ln3+ = Eu3+ (1), Gd3+ (2) and Tb3+ (3); H4pmd = 1,4-phenylenebis(methylene)diphosphonic acid] were prepared by using three distinct approaches: (i) conventional hydrothermal synthesis (180 °C, 3 days); (ii) microwave-assisted heating (50 W irradiation power, 40…

Transposition of chirality from diphosphonate metal–organic framework precursors onto porous lanthanide pyrophosphates Abstract Chiral porous inorganic materials, lanthanide pyrophosphates, were prepared from chiral porous metal–organic framework precursors, which upon thermal decomposition transpose their chirality and porosity onto the inorganic framework. It is argued that this synthesis concept may be extended to other chiral porous inorganic…

Analysis of the microcrystalline inclusion compounds of triclosan with β-cyclodextrin and its tris-O-methylated derivative. Abstract Solid 1:1 inclusion compounds of triclosan with native and permethylated 6-cyclodextrin (beta-CD and TRIMEB) were prepared by co-crystallisation and co-evaporation, respectively, and studied by FT-IR and C-13{H-1} CP/MAS NMR spectroscopies, thermogravimetric analysis, X-ray diffraction and theoretical calculations. Results showed that…
