Tuning the anticancer properties of Pt(ii) complexes structurally flexible -(2-picolyl)salicylimine ligands.

Three tridentate Schiff base ligands were synthesized from the reactions between 2-picolylamine and salicylaldehyde derivatives (3-ethoxy (OEt), 4-diethylamino (NEt) and 4-hydroxy (OH)). Complexes with the general formula Pt(N^N^O)Cl were obtained from reactions between the ligands and KPtCl. The ligands and their complexes were characterized by NMR spectroscopy, mass spectrometry and elemental analysis.

Synthesis and Characterization of Bipyridine-Based Polyaminal Network for CO Capture.

The response to the high demand for decreasing the amount of CO in the atmosphere, a new polyaminal-based polymer network was designed and successfully prepared through one-pot polycondensation reaction of melamine and [2,2'-Bipyridine]-5,5'-dicarbaldehyde. The formation of the polymer structure was confirmed by FT-IR, solid-state C NMR, and powder-X-ray diffraction. The porous properties of the polymeric structure were confirmed by field-emission scanning electron microscope and N adsorption-desorption methods at 77 K.
