Abstract

The invention discloses an application and a use method for 5-(2-methoxy-phenoxyl)-2, 2'-bi-pyrimidyl-4, 6-diphenol. After the tetrahydrofuran solution of the 5-(2-methoxy-phenoxyl)-2, 2'-bi-pyrimidyl-4, 6-diphenol is reacted with alkali, an ultraviolet spectrum and fluorescence spectrum are remarkably changed, the 5-(2-methoxy-phenoxyl)-2, 2'-bi-pyrimidyl-4, 6-diphenol can be applied to a pH fluorescent sensor, and the detected pH value is ranged from 6.2 to 9.9. A series of molecular logic gates based on alteration of fluorescence such as INHIBIT, NOR, COR, and the like, can be designed and constructed by using the special photochemical property of the molecular, the three basic logic gates are properly combined, and then a two input/three output complex logical system can be also constructed. The invention has high sensitivity as the pH fluorescent sensor, and the low detection limit plays the role in the microenvironment of biological tissues, cells and membranes and in the pH detection of reagent and fluid, and the like; and in the application aspect of the molecular logic gate of the optical signal, the molecular logic gate is the basic element of the chemical computer, thereby the invention has very broad application prospect and high application value.

Description

technical field [0001] The present invention relates to the use and method of 5-(2-methoxy-phenoxy)-2,2'-bipyrimidinyl-4,6-diol. Background technique [0002] The use of fluorescence method as a means of analysis and detection has the advantages of high sensitivity and low detection limit. In recent years, due to the continuous emergence of new concepts, new theories, and great progress in experimental techniques, fluorescence methods have also undergone significant development in analytical applications. For example, the principle of intramolecular charge transfer (Intramolecular Charge Transfer ICT) is used to construct a fluorescent sensing system, which has been widely used to detect metal cations, anions, acid-base pH values, etc. in life and the environment. Several pH fluorescent sensors based on the principle of Photoninduced Electron Transfer PET that have been reported have either low detection sensitivity (the spectral change is not obvious), or the fluorescence ...
