法国图卢兹第三大学（Universite Toulouse III - Paul Sabatier) CNRS-LBPB课题组Dr. Didier Bourissou和Prof. Blanca Martin Vaca现根据实验室需求需招收一名聚合物方向博士生，预计2025年9月或10月入学。关于LBPB的更多信息可通过课题组网站了解：https://lhfa.cnrs.fr/index.php/en/teams/lbpb-en/accueil-lbpb-en. (备注：这里的老师都非常友善和耐心，有问题老师都会积极帮你解决，课题组氛围活跃，欢迎感兴趣的同学加入我们。) 研究内容：聚焦于新型功能化单体的设计及其开环（共）聚合，以制备具有可控结构和性能的可降解聚合物。 研究包括：（i）新单体与共聚合物的合成及催化，（ii) 聚合物性能（降解、包裹能力等）的分析，(iii)解聚回收单体的闭环过程。 申请要求：候选人需具备分子化学及合成经验，有聚合物化学背景者优先。熟悉相关表征技术，如nmr, IR, SEC, MALDI-TOF等，并具备一定的英语能力（可提供语言证明）和团队精神。 感兴趣的申请者可直接联系：blanca-maria.martin-vaca@univ-tlse3.fr / didier.bourissou@univ-tlse3.fr 更多信息参见下面的英文部份： Context. Aliphatic polycarbonates and polyesters concentrate considerable attention not only in the medical field, due to their biodegradable character, but also for packaging and other commodity applications, thanks to additional suitable physical properties,1 as well as chemical recyclability.2 Further developments in these areas require reliable access to a broad range of polycarbonates / polyesters with different and well-controlled structures. One method to achieve this goal is the ring-opening (co)polymerization (ROP) of tailor-made monomers, which permits to tune the polymer properties by introducing new functional groups either on the polymer backbone or as a lateral group. It is thus very desirable to improve the access to functionalized monomers and to develop reliable methods for their controlled (co)polymerization. Our team has strong expertise in the development of catalytic systems (organic and dual systems) capable to promote controlled ROP of lactones and cyclic carbonates leading to biodegradable polymers of tuned properties.3 On the other side, we have recently reported three new monomers A-C (based on lactones and cyclic carbonates) designed for giving access to modified polyesters and polycarbonates.4 Objectives. In this PhD project, we aim to prepare new monomers by structural modulation of monomers A-C in order to impart new properties to the ensuing copolymers. The organocatalyzed polymerization of the new monomers will be investigated, as well as their copolymerization with appropriate co-monomers (lactones or cyclic carbonates). The impact of new functional groups on the properties of the polymers (degradation rates, self-segregation properties, encapsulation of active ingredients …) and the closing-loop by depolymerization back to the monomer will also be investigated. This is a multidisciplinary project involving: (i) synthetic and catalytic methodologies for the preparation of new monomers and (co)polymers, (ii) a large span of analytical methods (multi-nuclear NMR, IR spectroscopy, Maldi-TOF mass spectrometry, size-exclusion chromatography…), and (iii) investigation of the (co)polymer properties and applications. |
