Usage

General Description

DL-Camphorquinone, often abbreviated as CQ, is a yellow crystalline solid and a type of ketone that is typically derived from the natural compound camphor. Its primary use is in the polymer industry as a photoinitiator, where it begins the polymerization process when exposed to light. In dentistry, it is used in light-cured dental fillings and restorative materials to encourage the hardening process. Despite its widespread use, exposure to DL-Camphorquinone can cause skin and eye irritation, and prolonged inhalation may result in harm. Therefore, it must be handled with care, typically through the use of gloves and eye protection.

A phenanthroline-derived ligand and its complexation with Pd(II): From ligand design, synthesis and Pd(II) complexes structures to its application

A novel phenanthroline-derived bis-opened-triazine ligand for selective complexation with Pd(ii) over 19 typical metals from HNO3 media was designed based on cavity modulation strategy. Structures of the three species of the Pd(ii) complexes of with the ligand were elucidated by 1H NMR titration isothermal titration calorimetry (ITC) and density functional theory (DFT) studies. ITC test and binding energy calculations demonstrated that the asymmetrical 1:1 Pd(ii)-ligand complex with a monodentate nitrate anion was the most stable among these three species of the Pd(ii) complexes. The excellent kinetics of Pd(ii) extraction with the ligand is due to its optimal conformation completely ready for metal ligation. The enhanced special extraction selectivity and fast extraction rate towards Pd(ii) achieved by the phenanthroline-derived ligand demonstrated that the effective separation of some radionuclides with smaller radius in HLW through cavity modulation strategy is a feasible approach.
