Amphiphilic oligo(2-ethyl-2-oxazoline)s via straightforward synthesis and their self-assembly behaviour

Abstract

The synthesis of poly(2-oxazoline)s offers an unparalleled degree of functionalization when fabricating smart, functional polymers for biomedical uses. The termination of 2-oxazoline polymerisations by direct endcapping can be exploited to...

Utilization of Anthracene-Functionalized Poly(2-oxazolines) as a Dispersant of Carbon Black in Water and Dodecane

“…Moreover, further end-group analysis of P1 and P2 by MALDI-TOF spectrometry revealed greater functionalization compared to NMR; a recent study found a similar observation where MALDI analysis disclosed the presence of only the end-capped product, indicating higher functionalization efficiency compared to NMR analysis . The MALDI analyses of P1 and P2 , shown via Figure and Figure S3, both displayed a primary distribution that matched closely with the calculated molecular weight, with an average repeating unit of 99.1, which is identical to the molecular weight of the EtOx monomer repeating unit.…”

“…In recent years, this methodology has been exploited for a range of studies and applications. 45,46 Herein, we utilize these accessible techniques to synthesize a library of POxs with varying degrees of polymerization and anthracene functionalization; this is conveyed via Scheme 1. Direct end-capping of 9-anthracenecarboxylic acid onto poly(2ethyl-2-oxaozline) (PEtOx) and poly(2-isostearic-2-oxazoline) (PiStOx) is demonstrated for the first time to the best of our knowledge.…”

“…A variety of nucleophiles, such as amines, thiols, and carboxylic acids, can be used to terminate the POx chain, and the ability to further functionalize the α-chain end offers incredible flexibility and control on the physical and chemical properties of POx-based materials. In recent years, this methodology has been exploited for a range of studies and applications. , …”
