Facile Layer Diffusion Technique for Synthesis of Terbium-Based Metal Organic Framework for Fluorometric Sensing of Hydroquinone.

A photoluminescent terbium (III)-based Metal Organic Framework (MOF) was synthesized at room temperature by layer diffusion method utilizing mixed carboxylate linkers (4,4'-oxybis(benzoic acid) and benzene-1,3,5 tricarboxylic acid). Synthesized MOF has crystalline nature and rod-shaped morphology and is thermally stable up to 455 °C. The fluorescence emission spectra and theoretical results revealed that carboxylate linkers functioned as sensitizers for Tb(III) photoluminescence which resulted in four distinct emission peaks at 495, 547, 584, and 621 nm corresponding to the transitions D → F, D → F, D → F, and D → F.

Schiff base-functionalized metal-organic frameworks as an efficient adsorbent for the decontamination of heavy metal ions in water.

Adsorptive removal of heavy metal ions from water is an energy- and cost-effective water decontamination technology. Schiff base functionalities can be incorporated into the pore cages of metal-organic frameworks (MOFs) via direct synthesis, post-synthetic modification, and composite formation. Such incorporation can efficiently enhance the interactions between the MOF adsorbent and target heavy metal ions to promote the selective adsorption of the latter.

The sensing of ions was accompanied by colorimetric change (for Cu) as well as emission turn-off response.

A review of current treatment strategies based on cisplatin for leishmaniosis.

Neglected tropical diseases as termed by World Health Organization include a group of 20 diverse infectious diseases in the tropical and subtropical regions of the world. Amongst these diseases, high mortality rate is mostly associated with Chagas disease and leishmaniosis due to limited drugs, severe toxicity caused by the available drugs and drug resistance. The above hitches have triggered the researchers to focus on the development of novel alternative therapeutics.
