Abstract

The invention relates to a phosphor-containing crown macromolecular hybrid nanometer material and a preparation method and application thereof. The phosphor-containing crown macromolecular hybrid nanometer material is characterized in that phosphonitrilic chloride trimer is used as a core to synthesize novel phosphor-containing crown macromolecules by a layered modifying method, the surface is modified with pyridine, the novel phosphor-containing crown macromolecule of which the surface contains metal ion chelating sites is obtained, and the copper ions and gold ions are directly complexed, soas to form the hybrid nanometer material for preparing anti-tumor drugs. The phosphor-containing crown macromolecular hybrid nanometer material has the advantages that the raw materials are commercialized, the molecular weight of the prepared phosphor-containing crown macromolecule is uniform, the preparation method is simple, the controllability of reaction process is high, the operation is easy, and a plurality of metal ion chelating sites is contained; the prepared hybrid nanometer material can be applied to the anti-tumor study, and the good application prospect is realized.

Description

Technical field [0001] The invention belongs to the technical field of functional hybrid nano-materials, and particularly relates to a pyridine-modified phosphorus-containing crown macromolecular-based hybrid nano-material, and a preparation method and application thereof. Background technique [0002] Phosphorous dendrimers (Phosphorous dendrimers) are more uniform in molecular weight distribution than traditional polyamidoamine dendrimers (PAMAM), their molecular structure is highly dispersible, and the three-dimensional structure and surface chemistry can be precisely controlled. It has attracted wide attention from researchers. With the continuous development of nanotechnology and nanomedicine, phosphorus-containing dendrimers are used as nanocarriers or scaffolds, providing the possibility for the delivery of a variety of anti-tumor drugs and the design of biologically active compounds. They have been widely used in catalysis, materials, and biology. And other fields. Howe...
