Medientyp: E-Artikel Titel: Synthesis of amphiphilic dendronized polymers to study their self‐assembly and transport behavior Beteiligte: Kumari, Meena; Singh, Abhishek Kumar; Kumar, Shiv; Achazi, Katharina; Gupta, Shilpi; Haag, Rainer; Sharma, Sunil K. Erschienen: Wiley, 2014 Erschienen in: Polymers for Advanced Technologies, 25 (2014) 11, Seite 1208-1215 Sprache: Englisch DOI: 10.1002/pat.3293 ISSN: 1042-7147; 1099-1581 Entstehung: Anmerkungen: Beschreibung: Herein, we report on the synthesis of PEG‐1000‐diethyl ester and 2‐azido‐propane‐1,3‐diol‐based copolymers utilizing Novozym 435 (Candida antarctica lipase) using a biocatalytic method. The linear base copolymer was then functionalized with polyglycerol‐based regular [G1.0] and [G2.0] dendrons and C12/C14 hydrophobic alkyl chains via an efficient “Click approach.” The resulting amphiphilic dendronized polymers form well‐defined micelles in aqueous solutions. The transport behavior of these polymers was studied by using Nile red as a fluorescent model dye. The cytotoxicity profiles of a few representative polymers were evaluated, and the effect of hydrophobic alkyl chain length as well as the hydrophilic polyglycerol dendron's generation on the biocompatibility of polymeric systems was studied.
