The present disclosure provides an organic compound, an electron transport material, and an application thereof. The organic compound has a structure as shown in Formula I. Design of molecular structure and substituents enables it to undergo tridentate coordination or tetradentate coordination with metal, and more stably and firmly combination with metal, so that it has stronger stability and longer working life when used as an electron transport material, which effectively solves a problem of rising drift voltage. The organic compound has greater rigid distortion, which can suppress an increase of intermolecular attraction and prevent it from forming a planar structure to cause excessive intermolecular attraction. The organic compound is used as an electron transport material, and can be applied to an electron transport layer and/or an electron injection layer of an OLED device, which can effectively improve luminous efficiency and working life of the device, and reduce turn-on voltage.

The silyl phosphine compound of the present invention is represented by the formula (1) and has an arsenic content of not more than 1 ppm. The process for producing a silyl phosphine compound of the present invention is a process comprising mixing a basic compound, a silylating agent and phosphine to obtain a solution containing a silyl phosphine compound, removing a solvent from the solution to obtain a concentrated solution of a silyl phosphine compound, and distilling the concentrated solution, wherein an arsenic content in the phosphine is adjusted to not more than 1 ppm by volume in terms of arsine. The process for producing InP quantum dots of the present invention uses, as a phosphorus source, a silyl phosphine compound represented by the formula (1) and having an arsenic content of not more than 1 ppm by mass. ##STR00001## (For definition of R, see the specification.)
