Diels-Alder 클릭 반응을 이용한 Diselenide 가교 구조를 가지는 고분자 마이셀의 합성 및 특성 연구
- Abstract
- 공유 결합은 미셀 코어의 안정성을 향상시키는 방법 중 하나이다. 클릭 화학은 폴리머 변형에 광범위하게 적용되어 공유 가교 결합에 대한 신뢰할만한 전략이되었습니다. 이 연구에서 우리는 poly (ethylene oxide) -b-poly (furfuryl methacrylate) (PEO-b-PFMA)를 기반으로 한 자극 및 빛 반응 코어 가교 미셀의 합성과 특성을보고했다. 양친 매성 블록 공중 합체는 단일 전자 이동 리빙 라디칼 중합 (SET-LRP)을 통해 합성되었다. Diels-Alder 클릭 반응을 사용하여 촉매없이 diselenide 함유 가교제를 사용하여 코어 가교 미셀을 형성 하였다. 환원 - 산화 조건 및 근적외선 노출 하에서의 코어 가교 미셀의 안정성이 본 연구에서 연구되었다.
The covalent crosslinking is one of the methods to enhance the stability of micellar core. Click chemistry became a reliable strategy for covalent crosslinking due to the wide application of the polymeric modification. In this work, we reported the synthesis and characterization of stimuli and light responsive core-crosslinked micelles based on poly-(ethylene oxide)-b-poly (furfuryl methacrylate) (PEO-b-PFMA). The amphiphilic block copolymers were synthesized via single electron transfer living radical polymerization (SET-LRP). Diels-Alder click type reaction was employed to form core-crosslinked micelles using a diselenide-containing crosslinker without any catalyst. The stability of core-crosslinked micelles under the reductive-oxidative condition and near infrared exposure was investigated in this work.
