Astaxanthin-based polymers as new antimicrobial compounds

10.1039/C7PY00663B

2017-06-27

A library of novel high molecular weight polymers based on the natural carotenoid astaxanthin (ATX) has been successfully synthesized. ATX is a powerful antioxidant, known for its various therapeutic properties including anti-inflammatory and antimicrobial ac...

Evaluation of an external initiating Ni(II) diimine catalyst for electron-deficient π-conjugated polymers

10.1039/C7PY00873B

2017-06-27

We have prepared, isolated, and evaluated the first Ni(II) diimine catalyst able to externally initiate the Kumada catalyst transfer polymerization of an electron-deficient π-conjugated monomer. The catalyst installs an o-methoxyphenyl group at the initiating...

Facile construction of crosslinked anion exchange membranes based on fluorenyl-containing polysulfone via click chemistry

10.1039/C7PY00789B

2017-06-27

A series of fluorenyl-containing polysulfone-based crosslinked anion exchange membranes with high conductivity and excellent stability were fabricated via click chemistry. Azide groups were firstly introduced into the side chains of fluorenyl-containing polys...

Effects of molecular weight distribution on the self-assembly of end-functionalized polystyrenes

10.1039/C7PY00803A

2017-06-27

The molecular weight distribution (MWD) of polymers shows effects on their phase separation, crystallization, self-assembly, and mechanical properties. It is well known that the architecture of polymers plays a crucial role in the self-assembly of patterned p...

All-conjugated P3HT donor PCDTBT acceptor graft copolymers synthesised via a grafting through approach

10.1039/C7PY00612H

2017-06-27

A generally applicable synthetic method for all-conjugated graft copolymers is presented. By using an PCDTBT acceptor backbone and poly(3-hexylthiophene) (P3HT) grafts, all conjugated graft copolymers are synthesized using a grafting-through strategy which pe...

RAFT-mediated, visible light-initiated single unit monomer insertion and its application in the synthesis of sequence-defined polymers

10.1039/C7PY00713B

2017-06-26

In this communication, we report a catalyst-free methodology for single unit monomer insertion (SUMI) into reversible addition–fragmentation chain transfer (RAFT) agents initiated by low intensity visible light. This method is applicable to broad range of mon...

The terpolymerization of ethylene and propylene with isoprene via THF-containing half-sandwich scandium catalysts: a new kind of ethylene–propylene–diene rubber and its functionalization

10.1039/C7PY00847C

2017-06-26

The terpolymerization of ethylene and propylene with isoprene was performed catalyzed by half-sandwich scandium complexes (C5Me4SiMe3)Sc(CH2SiMe3)2(THF) (1) and [1,3-(Me2Si)2C9H5]Sc(CH2SiMe3)2 (THF) (2) in combination with 1 equiv. of [Ph3C][B(C6F5)4]. The te...

Retinol initiated poly(lactide)s: stability upon polymerization and nanoparticle preparation

10.1039/C7PY00881C

2017-06-26

The synthesis of retinol initiated polylactide (PLA) by ring opening polymerization (ROP) of L-lactide via in situ calcium alkoxide formation with all-trans-retinol and Ca[N(SiMe3)2]2(THF)2 is described. PLAs with degree of polymerization (DP) values ranging ...
