IODINE COMPLEX AND PREPARATION METHOD THEREFOR AND USE THEREOF
20210292443 · 2021-09-23 ·

An iodine complex is formed by complexing a unit having a structure as represented by formula (I) with iodine molecules or iodine molecules with polyiodide ions formed by combining iodine ions. As a carrier, a polymer is complexed with iodine to obtain an iodine complex for formula (I).

##STR00001##

The iodine complex can be used as a radioactive marker, or used in an iodine therapeutic agent, or used in a polarizer. The polymer carrier has good biocompatibility. The content of iodine in the iodine complex can be adjusted according to requirements, and the content of the iodine can be adjusted within a range of 0.001-60%. The difference in the content of the iodine can affect the transmission clarity of the iodine complex as a radiographic marker.
