We introduce the first example of isoreticular titanium–organicframeworks, MUV‐10 and MUV‐12, to show how the different affinity of hard Ti(IV) and soft Ca(II) metal sites can be used to direct selective grafting of amines. This enables the combination of Lewis acid titanium centers and available ‐NH2 sites in two sizeable pores for cooperative cycloaddition of CO2 to epoxides at room temperature

The present invention relates to monocrystalline metal organic frameworks comprising chromium ions and carboxylate ligands and the use of the same, for example their use for storing a gas. The invention also relates to methods for preparing metal organic frameworks comprising chromium, titanium or iron ions and carboxylate ligands. The methods of the invention allow such metal organic frameworks to be prepared in monocrystalline or polycrystalline forms.

Nasal gliomas are rare, benign, congenital, midline tumors. They are seen most commonly in neonates and children but rarely in adults. We encountered in a 28-year-old woman a rare case of nasal glioma presenting as bilateral total blindness. The tumor was present in both nasal fossae. It extended into the parasellar region, with erosion of the cribriform plate and medial wall of the right orbit.
