Description

technical field [0001] The invention relates to the technical field of synthesis of new chemical materials, in particular to a substituted pyridine complex, a preparation method thereof and an application as a near-ultraviolet photoluminescent material. Background technique [0002] Luminescent materials, also known as luminous bodies, are functional materials that can convert various forms of energy absorbed from the outside into non-equilibrium light radiation. There are two types of light radiation, equilibrium radiation and non-equilibrium radiation, namely thermal radiation and luminescence. As long as any object has a certain temperature, the object must have radiation (red light, infrared radiation) that is in thermal equilibrium with this temperature. Non-equilibrium radiation means that under the excitation of some external action, the system deviates from the original equilibrium state. If the object returns to the equilibrium state, its excess energy is released ...
