Conjugated polymer material with nuclear magnetic resonance imaging function and preparation method thereof

The invention belongs to the technical field of biomedical materials, and particularly relates to a conjugated polymer nano-material with a nuclear magnetic resonance imaging function and a preparation method thereof. According to the invention, the polymerization process of conjugated polymer monomers is regulated and controlled by using small molecules containing catechol units, so that the optical and paramagnetic properties of the material are regulated and controlled, a series of nano-materials with a magnetic resonance imaging function and a second near-infrared diagnosis and treatment function are prepared, and the application range of the conjugated polymer nano-materials is expanded. 本发明属于生物医学材料技术领域，具体为一种具有核磁共振造影功能的共轭聚合物纳米材料及其制备方法。本发明使用含有邻二酚单元的小分子调控共轭聚合物单体的聚合过程，从而调控材料的光学和顺磁性能；制备得到一系列具有磁共振造影功能和第二近红外诊疗功能的纳米材料，拓展了共轭聚合物纳米材料的应用范围。
