Title:
SILYL PHOSPHINE COMPOUND, METHOD FOR PRODUCING SILYL PHOSPHINE COMPOUND AND METHOD FOR FORMING InP QUANTUM DOT
Document Type and Number:
WIPO Patent Application WO/2019/188680
Kind Code:
A1
Abstract:
The silyl phosphine compound according to the present invention is represented by formula (1) and has an arsenic content of 1 ppm or less. The method according to the present invention for producing a silyl phosphine compound comprises: mixing a basic compound, a silylating agent and phosphine to give a solution containing a silyl phosphine compound; removing the solvent from the solution to give a liquid concentrate containing the silyl phosphine compound; and then distilling the liquid concentrate, wherein the arsenic content of the phosphine is regulated to 1 ppm by volume or less in terms of arsine. In the method according to the present invention for forming an InP quantum dot, a silyl phosphine compound that is represented by formula (1) (wherein R is as defined in the description) and has an arsenic content of 1 ppm by mass or less is used as a phosphorus source.
