Post-modification of poly(pentafluorostyrene): a versatile “click” method to create well-defined multifunctional graft copolymers

Abstract

This communication reports a versatile post-modification reaction of poly(pentafluorostyrene) building blocks in order to design multifunctional graft copolymers by taking advantage of the selective replacement of the para-fluorine groups.

Metallo‐Supramolecular Materials Based on Amine‐Grafting Onto Polypentafluorostyrene

“…In our previous work, it was demonstrated that the nitroxide‐mediated polymerization (NMP) of 2,3,4,5,6‐pentafluorostyrene proceeds in a controlled manner with a terpyridine functionalized TIPNO‐based alkoxyamine 24. Subsequent post‐modification of the para ‐fluorine group with different amines was demonstrated for the preparation of various graft copolymers bearing a terpyridine moiety at one terminal chain end 21. In this contribution, we extend this synthetic approach toward the synthesis of metallo‐ supramolecular (block) copolymers.…”

“…Previously, we have described a synthetic approach affording well‐defined graft copolymers by selectively replacing the para ‐fluorine substituents of poly(pentafluorostyrene) with amines 21. The versatility of this straightforward modification reaction, performed under microwave heating, was demonstrated by substituting the para ‐fluorine groups with 5‐aminopentanol providing direct access to a variety of chemical modification reactions including the initiation of ring‐opening polymerizations as well as esterification reactions.…”

Arylierungschemie für die Biokonjugation

“…In den darauffolgenden Jahrzehnten konzentrierte sich die Anwendung der Perfluoraryl-Thiol-Reaktion hauptsächlich auf synthetische Moleküle,insbesondere Modifikationen von Porphyrinoiden [90] und synthetischen Polymeren [91][92][93] (Abbildung 10). 1991 berichteten Mansuy und Mitarbeiter über die S N Ar-Reaktionen von Te tra(pentafluorphenyl)porphyrin mit verschiedenen Nukleophilen.…”

Using Metallo‐Supramolecular Block Copolymers for the Synthesis of Higher Order Nanostructured Assemblies

“…These two polymers were then linked together via a ruthenium(II) complex using chemistries previously established by Schubert and coworkers. [36,97] This amphiphilic diblock self-assembled via the slow addition of water to a homogenous DMF solution of the copolymer, followed by dialysis, forming uniform micelles, which were observable by DLS (D h ¼ 79 AE 3 nm) and TEM (D avg ¼ 45 AE 4 nm). Furthermore, in a departure from conventional metallo-supramolecular polymer micelles, these non-covalently connected micelles [18,98] were then covalently cross-linked in their PAA shell domain (ca.…”
