Description

technical field [0001] The invention belongs to the technical field of medical biological detection, and specifically relates to a biscalix[4]arene derivative and a metal complex thereof, a synthesis method and an application thereof. Background technique [0002] Molecular recognition is the process in which the subject (receptor) selectively binds to the guest (substrate) and produces a specific function. The recognition process may cause changes in the magnetic, electrical, optical properties and conformation of the system, resulting in the storage, transmission and processing of chemical information. Therefore, molecular recognition plays an important role in information processing and transmission, and in the fabrication of molecular and supramolecular devices. [0003] Molecular recognition using the change of magnetic or fluorescent properties caused by the combination of host and guest molecules is the main research direction at present, and has a wide range of appl...
