Usage

General Description

(N,N-Dimethylamino)triethylsilane is a chemical compound used mainly in the field of chemistry for various reactions. It belongs to the class of organosilicon compounds, typically exist as colorless to light yellow liquid, often characterized by their high reactivity. (N,N-DIMETHYLAMINO)TRIETHYLSILANE is noted for its notable role in the formation of functional groups of organic compounds, thanks to its silicon and nitrogen atoms. Its reactivity and nucleophilic properties make it suitable for forming silicon-containing polymers and in chemical vapor deposition for producing semiconductors. However, (N,N-Dimethylamino)triethylsilane is flammable and it needs to be handled with care due to its potentially harmful properties if ingested, inhaled or comes in contact with skin, and may cause severe burns and eye damage.

Sterically encumbered tris(trialkylsilyl) phosphine precursors for quantum dot synthesis

The synthesis of nanomaterials with a narrow size distribution is challenging, especially for III-V semiconductor nanoparticles (also known as quantum dots). Concerning phosphides, this issue has been largely attributed the use of overly reactive precursors. The problem is exacerbated due to the narrow range of competent reagents for III-V semiconductor syntheses. We report the use of sterically encumbered tris(triethylsilyl) phosphine and tris(tributylsilyl) phosphine for InP quantum dot (QD) synthesis among others. The hypothesis was that these reagents are less reactive than the near-ubiquitous precursor tris(trimethylsilyl) phosphine and can be used to create more homogeneous materials. It was found that the InP products' quantum yields and emission color saturation (fwhm) were improved, but not to the levels realized in CdSe QDs. Regardless, these reagents have other positive attributes; they are less pyrophoric and can be applied toward the synthesis of II-V semiconductors and organophosphorus compounds. Concerning safe practices, we demonstrate that ammonium bifluoride is an effective replacement for highly toxic HF for the post-treatment of III-V semiconductor quantum dots.

REACTION OF THE NITROGEN-CONTAINING HETEROANALOGS OF ACETALS WITH TRIETHYLSILANE

The reaction of 1,3-oxaazacycloalkanes with triethylsilane in the presence of a nickel catalyst and zinc halides was investigated.The new compounds of the triethylsilyloxy(dialkylamino)alkane type, i.e., products from the chemospecific cleavage of the heterocycle at the C2-O bond, were isolated and characterized.It was established that triethylsilane can cleave the C-N bond in acyclic aminals with the formation of triethyl(dialkylamino)silanes and tertiary amines.
