Iridium-complexed nanosize phosphors 3D-encapsulated with nine 3,6-di-tert-butyl-N-propyl-carbazole groups were constructed as host-dopant integrated systems, which achieved a high photoluminescence quantum yield beyond 70% from neat evaporated films, and

The synthesis of four novel non-symmetric Ni(ii)-POCOP pincer complexesmeta-functionalized with either benzothiazole or benzimidazole at the central aryl ring is described. All complexes were fully characterised in solution by various analytical techniques and the molecular structures in the solid state of complexes1b,2aand2bwere unequivocally determined by single crystal X-ray diffraction analysis. In addition, the Ni(ii)-POCOP pincer complexes were efficiently used as catalysts in the synthesis of diarylketones by cross-coupling reactions of functionalized benzaldehydes and boronic acid derivatives under relatively mild conditions. An important aspect of this transformation is the dependence on the steric properties of the donor groups (OPR2) of the pincer ligands, the more active compounds having the phosphinitos bearing isopropyl groups (1aand2a) than those containingtert-butyl substituents (1band2b).
4,5-Imidazoledicarboxylic acid immobilized on Fe3O4 magnetic nanoparticles: Preparation, characterization, and application as a recyclable and efficient nanocatalyst in the sonochemical condensation reaction

An ever-increasing incidence of skin neoplastic diseases is registered. Therefore, it is important to protect the skin from the UV radiation that reaches the epidermis and dermis but also to block ROS generated by them. Our attention was attracted in deve
