摘要:The present invention relates to a method for the synthesis of semiconductor nanoparticles comprising elements of the groups IB, IIB, IIIA, IVA, VA or VIA of the periodic classification wherein the composition of the core nanoparticle is selected from the group consisting of IB-VIA, IIB-VIA, IIIA-VIA, IB-IIIA-VIA or IB-IIB-TVA-VIA, IIB-IIIA-VIA, IIB-TVA-VA or mixtures thereof, and at least one shell comprises elements of the groups IIB and VIA,, wherein in case the core composition is IIB-VIA the shell comprises at least a further element selected from the groups IB, IIIA, IVA or VA, using metal precursors comprising non- or weakly coordinating anions. It further relates to the consecutive process for the synthesis that includes first the preparation of a binary nanoparticle system then modified to make a ternary system which again can be further modified to make a quaternary system.

标题:Transformative synthesis of semiconductor nanoclusters with atomic precision via metal-ligand coordination exchange

摘要:Precision nanosynthesis is crucial for atomic engineering in nanostructures and mechanistic understanding of nanoscale reactions. But it is a daunting task due to emerging complexities in nanostructures and nanosynthesis. Here, we report the precision synthesis of semiconductor nanocluster via synergizing coordination, cluster, and colloidal chemistry at the nanoscale. In particular, by employing Cu26Se13(PEt2Ph)14 cluster and Cdl2(PPr3)2 coordination complex as precise precursors in colloidal cation exchange reaction, an atomically precise Cd26Se17I18(PPr3)10 cluster is produced at near- unity yield. X-ray crystallography reveals that the child CdSe cluster inherits its icosahedral-packed anion lattice and halide-phosphine-rich surface from parent cluster and complex respectively and further evolves into an enlarged structure. The hybridization of achiral precursors leads to chiral CdSe clusters co-crystallized as a 1:1 mixture of enantiomers. In-situ optical spectroscopy unveils that the reaction proceeds with well-defined pathways. Based on charge and coordination conservations, the structure of child cluster can be atomically linked to precursors via a series of transformations including surface coordination exchange, intra-cluster reorganization, and inter-cluster digestive ripening. The precision nanosynthesis with atomically defined precursors, pathways, and products is expected to further rationalize and diversify nanochemistry.
