Title: Semiconductor light emitting element and preparation method therefor
Inventor: LAN YUNG-LING
IPC: H01L33/00
Filed: 2018-03-12
Abstract: A semiconductor light emitting element and a preparation method therefor. A first cover layer (410) and a second cover layer (420) of the light emitting element grow between a final barrier layer (310) and an electron blocking layer (500) which have a high energy level, at a low temperature,. The first cover layer is an undoped layer which is grown at a relatively low temperature, and is used for decreasing the reduction of light emitting efficiency caused by diffusion of P-type impurity to a multiple quantum well structure layer (300). The second cover layer is a hole injection layer, which is doped with a high concentration of P-type impurity so as to improve the hole injection effect. Due to the first cover layer and the second cover layer having a high energy level, the invention efficiently reduces electron leakage, and improves the light emitting efficiency of the semiconductor element.

IPC: C07F5/04
Filed: 2018-04-17
Abstract: Disclosed is an application of 2,6-diisopropylanilino lithium in catalyzing hydroboration of a carbonyl compound and borane. In an anhydrous oxygen-free environment, borane is added in an inert gas atmosphere to a reaction flask having been subjected to dehydration and deoxidation treatment, then a catalyst 2,6-diisopropylanilino lithium is added and uniformly mixed, a carbonyl compound is further added to carry out hydroboration, and the reaction is terminated by exposure to air to obtain a borate. The present invention has found for the first time that 2,6-diisopropylanilino lithium can be extremely efficient in catalyzing the hydroboration of carbonyl compounds, and thus provides a novel solution for the preparation of borates by hydroboration of carbonyl compounds with borane. The 2,6-diisopropylanilino lithium has high catalytic activity in the hydroboration of the carbonyl compound and borane with mild reaction conditions, a short reaction time, and a high reaction yield. The reaction is simple and controllable, involves simple post-treatment, and employs a solvent-free system, thereby reducing environmental pollution. The disclosed catalyst is widely applicable to aromatic aldehydes (ketones) having different substitution positions and different electronic effects and to heterocyclic aldehydes (ketones) and fatty aldehydes (ketones), thereby providing more choices for obtaining borate compounds with different substituent structures.
