Abstract Exposure of soft material templates to alternating volatile chemical precursors can produce inorganic deposition within the permeable template (e.g. a polymer thin film) in process akin atomic layer (ALD). While such sequential infiltration synthesis (SIS) processes have now been demonstrated for many metal oxides, we report an SIS transition sulfide – CdS. Gas phase dimethyl cadmium and hydrogen infiltrated into poly(4‐vinylpyridine) films result 3D‐nucleation clusters consistent...

The energetically favorable formation of atomically precise clusters, known as magic size in the solution phase enables a precision nanoscale synthesis with exquisite uniformity. We report clusters via vapor infiltration atomic layer deposition precursors directly polymer thin film. Sequential trimethylindium and hydrogen sulfide gas into poly(methyl methacrylate) leads to uniform properties consistent cluster─In6S6(CH3)6. While an increase cluster might be expected additional sequential...
This study examines the relative binding strength of a series thiolate ligands to surfaces zincblende CdSe/ZnS core/shell quantum dots (QDs) passivated by phosphonate under basic conditions in water means isothermal titration calorimetry (ITC). A labile hydrophilic intermediate, 2-aminoethylphosphonic acid (AEP), was introduced place native hydrophobic carboxylate produce water-soluble QDs and provide universal starting point for competitive anionic exchange reactions. We introduce...
Colloidal quantum dots (QDs) are attractive fluorophores for bioimaging and biomedical applications because of their favorable tunable optoelectronic properties. In this study, the native hydrophobic ligand environment oleate-capped sphalerite CdSe/ZnS core/shell QDs was quantitatively exchanged with a set imidazole-bearing small-molecule ligands. Inductively coupled plasma-optical emission spectroscopy 1H NMR were used to identify quantify three different exchange processes: Z-type...
Energetically favorable formation of atomically precise clusters, known as magic-size clusters from solution phase synthesis are studied extensively enlightening their unique properties and consecutive nucleation growth mechanism to bulk structures. However, those vapor comparatively underdeveloped, especially for the metal chalcogenide materials. Here we report that sequential infiltration enables indium sulfide clusters. Based on experimental computational study, found reaction between...
