Problems solved by technology

[0004] At present, inorganic optical materials mainly use inorganic crystal LiNbO 3 , but it has disadvantages such as narrow modulation bandwidth, high half-wave voltage, and poor integrability; while organic optical materials have unique advantages such as fast response speed, large electro-optic coefficient, easy integration, and molecular design and tailoring, but they are reducing There is still room for improvement in terms of optical transmission loss and chemical stability at high temperature and polarization orientation stability

Description

technical field [0001] The invention belongs to the technical field of functional material synthesis, and in particular relates to a novel composite quaternary phosphonium salt, i.e. manganese tetrachloride-benzyl tris(4-methoxy)phenylphosphonium salt, its preparation method and fluorescence application. Background technique [0002] Luminescent materials, also known as luminous bodies, are a class of functional materials that can convert various forms of energy absorbed from the outside into electromagnetic radiation. Photoluminescence is the most common way of emitting light in luminescent materials. Since transition metal complexes have rich structural features and excellent properties such as luminescence, drugs, magnetism, and catalysis, they have attracted much attention since their synthesis. For example, Yin et al. studied the interaction between o-phenanthroline Ru metal complexes and DNA, making it further developed as a DNA fluorescent probe; Xiong et al. reporte...
