Abstract

The invention belongs to the field of supermolecular compound, and discloses a supermolecular compound, a preparation method thereof, and a method used for distinguishing microorganisms. The supermolecular compound possesses an inclusion complex structure composed of a conjugated polymer with a structure represented by formula (I), and cucurbituril [7], wherein R1 is used for representing one of structures represented by formula (II), formula (III), or formula (IV), n is used for representing an integer ranging from 30 to 300, R2, R3, and R4 are independently used for representing C1-C5 alkyl, Y is used for representing an alkylene with 6 to 12 carbon atoms, or one group with a general structure of -R5-O-R6- or -OR7-, R5, R6, and R7 are used for representing alkylenes, the carbon atom number of R7 ranges from 6 to 12, and X is used for representing a halogen. The method is high in speed, efficiency, and accuracy, and is convenient in distinguishing microorganisms such as bacteria, fungus, and virus.

Description

technical field [0001] The invention relates to the field of supramolecular compounds, in particular to a supramolecular compound and a preparation method thereof, a supramolecular compound prepared by the method, and a method for distinguishing microorganisms. Background technique [0002] The problem of drug resistance of pathogenic bacteria has become an urgent global problem that threatens human security. It has been proven that the misuse and abuse of fungicides in the fields of health care, agriculture and animal husbandry have led to the widespread emergence of drug-resistant pathogenic bacteria. For example, less than 20 percent of upper respiratory tract infections are caused by bacteria, yet patients often expect to be treated with antibiotics to which they are completely ineffective. Clinically, when a doctor diagnoses an infectious disease, the first thing to find out is whether it is caused by a bacterial or viral infection. But even for experienced doctors an...
