End-functionalized polymers by controlled/living radical polymerizations: synthesis and applications

This review focuses on end-functionalized polymers synthesized by controlled/living radical polymerizations and the applications in fields including bioconjugate formation, surface modification, topology construction, and self-assembly.

PDMAEMA-b-PPOA-b-PDMAEMA double-bond-containing amphiphilic triblock copolymer: synthesis, characterization, and pH-responsive self-assembly

This article reports a new pH-responsive double-bond-containing ABA triblock copolymer synthesized via a combination of free radical polymerization and SET-LRP.

The expanding field of polyphosphazene high polymers

The wide variety of accessible poly(organophosphazenes) is a consequence of the unusual macromolecular substitution approach to their synthesis.

Click-based porous inorganic–organic hybrid material (PHM) containing cyclophosphazene unit and their application in carbon dioxide capture

A high surface area porous hybrid material was synthesized by one-step click chemistry, which captures 1.83 mmol g⁻¹ CO₂ at 273 K.

Well-defined novel fluorene-containing polymers: synthesis, fluorescent properties, and micellar nanoparticles

We report the synthesis of a new monomer, 9,9-diethylfluoren-2-yl methyl methacrylate (FMMA) and its controlled reversible addition-fragmentation chain transfer (RAFT) homopolymerization to give PFMMA with narrow polydispersity indices (PDIs). The corresponding copolymerization with 2-(N,N-dimethylamino)ethyl methacrylate (DMAEMA) also gave well-defined block and random copolymers with controlled molecular weights and narrow PDIs. Their thermal behavior, UV-Vis absorption, and photoluminescent properties were studied. The PDMAEMA-b-PFMMA amphiphilic block copolymers showed self-assembly into aqueous spherical micellar nanoparticles with uniform size. The PFMMA core showed photoluminescence when carrying dichloromethane "guest" molecules and its emission was shown to be quenched after the release of the guest.

Polyphosphazene Elastomers, Gels, and Other Soft Materials

Nearly all soft materials are based on organic polymer molecules. In other words they are derived from macromolecules constructed around the chemistry of carbon. Yet there are roughly 100 other elements in the periodic table that could in principle provide the building blocks for polymers and for soft materials. A few "inorganic" elements are incorporated into gels and related materials. Examples include silicate, aluminate, and titanate sol-gel substances, but the opportunities for diversification within these systems are relatively limited. The poly(organosiloxanes) (silicones) were the first hybrid inorganic-organic polymers to be discovered and they continue to play a major role in research and technology. Nevertheless, a need exists for additional systems that have the structural diversity found in the field of organic polymers, combined with the attributes of inorganic skeletal elements rather than carbon. It is with this objective in mind that we have devoted several decades to exploring the synthesis and diversification of the polyphosphazenes.
