技術應用

Bench and commercial-scale production of functionalized trialkoxysilanes

詳細技術說明

UCLA researchers have developed a simple method of producing a wide variety of functionalized trialkoxysilanes using low power UV light. The pendant group, linked to the trialkoxysilane by a thioether bond, may be a small molecule, synthetic macromolecule, biomolecule or biopolymer. The method generally results in the formation of product trialkoxysilanes in high yield and purity, enabling product use without further purification. Furthermore, the invention is a low-cost method; synthesis does not require the use of noble metal catalysts, reactants and reagents are inexpensive, and only simple equipment is required.

State Of Development

Using the invention method, 14 different trialkoxysilane varieties were synthesized on a small scale (0.5-5 mmol) with near quantitative yields and high purities. One trialkoxysilane compound was also synthesized on a large scale (>100mmol, ~37g).

Background

Trialkoxysilanes are chemical compounds widely employed in research, commercial, and industrial settings. They and other members of the silane family have been used to modify or enhance material properties including surface wettability, adhesion, tribological/optical/electrical properties, and redox activity. While large varieties of trialkoxysilane are commercially available, many are also expensive. Moreover, current synthesis methods allow for only limited functionalization of trialkoxysilanes, a barrier that must be overcome to meet future demand for new silane-based materials and devices.
