The engineering of quantum dot solids with low defect concentrations and efficient carrier transport through a ligand strategy is crucial to achieve efficient quantum dot (QD) optoelectronic devices. Here, we study the consequences of various surface ligand treatments on the light emission properties of PbS quantum dot films using 1,3-benzenedithiol(More)
A pH-dependence of the Brønsted acid-catalyzed oxidation of sulfides to the corresponding sulfoxides with H₂O₂ is reported for the first time based on our systematic investigation of the catalytic performance of a series of Brønsted acids. For all of the Brønsted acids investigated, the catalytic performances do not depend on the catalyst loading (mol ratio(More)
The asymmetric unit of the title compound, (C(5)H(14)N(2))[SbCl(5)]·H(2)O, consists of an N-methyl-piperazinediium cation, a penta-chloridoanti-monate anion with the Sb(III) ion in a slightly distorted square-pyramidal coordination environment, and one solvent water mol-ecule. The crystal structure is stabilized by inter-molecular N-H⋯Cl, O-H⋯Cl and N-H⋯O(More)
