A fundamental understanding of the luminescence Au-thiolate nanoclusters (NCs), such as origin emission and size effect in luminescence, is pivotal to development efficient synthesis routes for highly luminescent Au NCs. This paper reports an interesting finding Au(I)-thiolate complexes: strong by mechanism aggregation-induced (AIE). The AIE property complexes was then used develop a simple one-pot NCs with quantum yield ~15%. Our key strategy induce controlled aggregation on situ generated...
ConspectusTotal synthesis, where desired organic- and/or biomolecules could be produced from simple precursors at atomic precision and with known step-by-step reactions, has prompted centuries-lasting bloom of organic chemistry since its conceptualization in 1828 (Wöhler synthesis urea). Such expressive science is also highly desirable nanoscience, it represents a decisive step toward atom-by-atom customization nanomaterials for basic applied research. Although total less established recent...
Iodine-doped Cu2Se shows a significantly improved thermoelectric performance during phase transitions by electron and phonon critical scattering, leading to dramatic increase in zT factor of 3–7 times culminating values 2.3 at 400 K.
This paper reports a simple and scalable method for the synthesis of highly fluorescent Ag, Au, Pt, Cu nanoclusters (NCs) based on mild etching environment made possible by phase transfer via electrostatic interactions. Using Ag as model metal, fast (total time < 3 h) cycle (aqueous → organic (2 h incubation) aqueous) has been developed to process originally polydisperse, nonfluorescent, unstable NCs into monodisperse, fluorescent, extremely stable in same (aqueous) protected thiol ligand....
Near-infrared II (NIR-II) imaging at 1100-1700 nm shows great promise for medical diagnosis related to blood vessels because it possesses deep penetration and high resolution in biological tissue. Unfortunately, currently available NIR-II fluorophores exhibit slow excretion low brightness, which prevents their potential applications. An atomic-precision gold (Au) cluster with 25 atoms 18 peptide ligands is presented. The Au25 clusters show emission 1100-1350 the fluorescence quantum yield...
