  Paramagnetic, amphiphilic, biocompatible polymers were prepared comprising a carbonate repeat unit bearing a paramagnetic organic radical, more specifically a nitroxyl radical. The radical polymers can be produced in one step from a precursor polymer bearing an active ester side chain by treating the precursor polymer with a radical-bearing nucleophile. The precursor polymer can be prepared by organocatalyzed catalyzed ring opening polymerization (ROP) of a cyclic carbonate monomer bearing an active ester side chain. The radical polymers can be non-toxic and partially biodegradable. The radical polymers have utility as contrast enhancing agents in a medical imaging application and/or as therapeutic agents for treating a medical condition. The radical polymers can also serve as carriers for therapeutic agents (e.g., drugs) and/or medical image enhancing agents (e.g., NIRF dyes).

  具有顺磁性、两性亲疏性、生物相容性的聚合物已经制备好，其中包含一个带有顺磁性有机自由基的碳酸酯重复单元，更具体地说是一个亚硝基自由基。这种自由基聚合物可以通过将带有活性酯侧链的前体聚合物与带有自由基的亲核试剂处理而一步制备而成。前体聚合物可以通过有机催化的环氧化聚合（ROP）来制备，该环氧化单体带有活性酯侧链。这种自由基聚合物可能是无毒且部分可生物降解的。这种自由基聚合物在医学成像应用中可用作增强对比剂，和/或作为治疗医疗状况的治疗剂。这种自由基聚合物还可以作为治疗剂（例如药物）和/或医学图像增强剂（例如NIRF染料）的载体。

  A one pot method of preparing cyclic carbonyl compounds comprising an active pendant pentafluorophenyl carbonate group is disclosed. The cyclic carbonyl compounds can be polymerized by ring opening methods to form ROP polymers comprising repeat units comprising a side chain pentafluorophenyl carbonate group. Using a suitable nucleophile, the pendant pentafluorophenyl carbonate group can be selectively transformed into a variety of other functional groups before or after the ring opening polymerization.
