Abstract: A capacitive coupler with asymmetric insulating layers includes a coupler transmitting side and a coupler receiving side. The coupler transmitting side includes a first insulating cavity, and a first plate and a second plate that are arranged on a first plane. The first insulating cavity is configured to enclose the first plate and the second plate with an insulating material. The coupler receiving side is arranged opposite to the coupler transmitting side and includes a second insulating cavity, a third plate and a fourth plate that are arranged on a second plane. The second insulating cavity is configured to enclose the third plate and the fourth plate with an insulating material. The first insulating cavity and the second insulating cavity have asymmetric insulating layers. The capacitive coupler can improve the power transfer efficiency and reduce the safety distance of the electric field.

Abstract: An organic light-emitting material, a method for the preparation thereof and use thereof are provided. The organic light-emitting material is a novel organic light-emitting material containing phosphine, has a high electron-transport property and a high fluorescence quantum efficiency, can be used as an emitting layer material and/or an electron transport layer material in an OLED element. Thus, an emitting layer and an electron transport layer in a traditional OLED element can be combined as one layer, thereby simplifying the structure and preparation process of the OLED element. Also, the organic light-emitting material has a specific response to oxygen, metal ions, etc., so that the organic light-emitting material can also be applied in the fields of chemo-biological detection, bio-imaging, anti-counterfeiting, etc. There are advantages of simple synthesis and purification, high yield, and adjustment of its luminous wavelength, luminous efficiency, etc. by introducing different functional groups.
