Novel molecular functional material-p-hydroxycinnamic acid

Metal organic coordination polymers as a new type of molecular functional materials, with its unique structure can be tailored, a variety of topological structures and in adsorption, catalysis, molecular recognition, ion exchange and optical, electrical, magnetic, chiral separation The potential for applications in other fields has attracted more and more attention from scientists. Among them, the coordination polymers constructed by transition metal and carboxylic acid ligands have become the current research hotspots. For example, metal light-emitting complexes are interposed between organic and inorganic substances, and have the advantages of high fluorescence quantum efficiency of organic substances. Because of the stable nature of inorganic materials, it is considered to be the most promising luminescent material.

The p-hydroxycinnamic acid produced by Hubei Yuancheng Company has two advantages as an excellent organic ligand. The first is that the product carboxylate has multiple coordination sites, which is very favorable for the synthesis of various complexes. At the same time, the hydroxyl groups easily form hydrogen bonds to form a stable complex. The second is that hydroxycinnamic acid itself has very good π-conjugated and has good luminescent properties. Therefore, p-hydroxycinnamic acid complexes may produce fluorescent properties that affect the performance of the unique luminescent materials.

Zhengzhou Institute of Light Industry has invented a patent that is a compound of p-hydroxybenzoic acid and phenanthroline compounded ruthenium complex and its preparation method and application. The patent found that the fluorescence spectrum data of the crystals of ruthenium complexes with p-hydroxybenzoic acid and phenanthroline showed that these complexes could emit stable solid-state fluorescence and could be used as fluorescent materials in the field of materials science. A discovery undoubtedly provided an opportunity for the application of hydroxycinnamic acid in the field of fluorescent materials.

With the further development of science and technology, the application of fluorescent materials in the market is becoming wider and wider. Apart from being used as a dye, fluorescent substances have also been widely used in organic pigments, optical brighteners, photooxidants, coatings, chemical and biochemical analysis, solar energy traps, anti-counterfeiting labels, drug tracers, and lasers.
