A catalyst refers to a substance that increases the rate of a reaction without changing the overall standard Gibbs free energy change of the reaction. Ligands represent atoms, molecules, and ions that can bond with a central atom (metal or metalloid). In general, ligands will donate at least one electron when participating in a bond. Two-phase catalysis of catalysts and ligands is the first application in the field of fluorine chemistry. The method of self-fluorine two-phase catalysis has developed rapidly, and a large number of new fluorine-based catalysts and ligands (especially phosphines) have been obtained in the field of chemistry.

Organic light emitting diodes (devices) or OLEDs are monolithic solid-state devices that typically consist of a series of organic thin films sandwiched between two thin film conductive electrodes. It is a display technology used in many electronic devices, such as smartphones, televisions, and wearables. In an OLED display, each pixel is made up of organic compounds that emit light when an electric current passes through them. Unlike traditional LCD displays, this eliminates the need for a backlight. As a result, OLED displays can achieve deeper blacks and higher contrast ratios, leading to vibrant and more realistic images.
