Kind Code:
A1
Abstract:
Provided are an iodine complex and a preparation method therefor and use thereof. The 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: (I). 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.
