The direct synthesis of copper selenide nanoparticles from the reaction of ditertiarybutyl selenide tBu2Se with copper(ii) trifluoroacetate Cu(TFA)2 under mild conditions is reported. The isolation of a molecular species during the course of this reaction, established as [Cu2(TFA)2(tBu2Se)3], by ...

Near-infrared plasmonic binary copper-based chalcogenides have found promising applications in photovoltaics and photothermal therapy. Here, we report a facile synthetic protocol for aqueous soluble covellite (CuS) nanocrystals (NCs) at room temperature. In contrast to previously reported routes, ...

We report on the synthesis of new dinucleating phenol-based “end-off” compartmental ligands HLMeH and HLMe2 bearing two different binding sites, one bis(2-methylpyridyl)aminomethyl (BPA) and one thiosemicarbazone (TSC) site, and their corresponding copper(II) complexes 1t and 2d. With the ligand ...

For three complex chemical reactions displaying intricate dynamics, we assess the effectiveness of a recently proposed quantitative method to forecast bursting and large spikes, i.e. extreme events. Specifically, we consider predicting extreme events in (i) a copper dissolution model where ...
