Here, we describe the design, synthesis, and evaluation of two kinds of multifunctional zwitterionic linear poly(carboxybetaine thiophene) (PCBTh) and porous poly(carboxybetaine thiophene-co-9,9′-bifluoreneylidene) (PCBTh-coBF) polymers, which can be facilely synthesized using Yamamoto and Suzuki polycondensation, respectively. The integrations of zwitterionic polymer-based biomaterials that consist of conjugated polymer backbones, multifunctional zwitterionic side chains, and distorted units are designed and studied to address a key challenge of conjugated polymers in biomedical applications: biofouling phenomena that eventually lead to the failure and reduced lifetime of bioelectronics in the body. The introduction of a twisting unit into the polymer backbone allows us to tune the porosity, morphology, optical properties, and efficiency of antibiofouling features of resulting polymers. The PCBTh-coBF coated surface exhibits good conductivity, stability, hydrophilicity, and antibiofouling properties against protein adsorption, cell growth, and bacteria attachment, which may be useful for chronic in vivo bioelectronics applications by minimizing the foreign body response.

两性离子多孔共轭聚合物作为抗生物污损植入式生物电子学的多功能平台。
在这里,我们描述了两种多功能两性离子线性聚(羧基甜菜碱噻吩)(PCBTh)和多孔聚(羧基甜菜碱噻吩-co -9,9'-二芴基)(PCBTh- co BF)聚合物的设计、合成和评估,可以分别使用 Yamamoto 和 Suzuki 缩聚法轻松合成。设计和研究由共轭聚合物主链、多功能两性离子侧链和扭曲单元组成的基于两性离子聚合物的生物材料的集成,以解决共轭聚合物在生物医学应用中的关键挑战:最终导致失效和寿命缩短的生物污垢现象体内的生物电子学。在聚合物主链中引入扭曲单元使我们能够调整所得聚合物的孔隙率、形态、光学性能和抗生物污损特性的效率。 PCBTh -co BF涂层表面表现出良好的导电性、稳定性、亲水性和抗蛋白质吸附、细胞生长和细菌附着的抗生物污染特性,这可能通过最大限度地减少异物反应而用于长期体内生物电子应用。
