- Aminobisphosphonate Polymers via RAFT and a Multicomponent Kabachnik–Fields Reaction
Patricia R. Bachler, Michael D. Schulz, Chelsea A. Sparks, Kenneth B. Wagener and Brent S. Sumerlin

Aminobisphosphonate polymers are synthesized via reversible addition-fragmentation chain transfer polymerization and multicomponent reactions. Polymerization of a protected amine monomer results in good control over molecular weights and polydispersity indices (PDIs). The deprotected amine is reacted with a phosphite and an aldehyde to install the aminobisphosphonate moiety.

Lanthanide-doped upconversion-luminescent nanoparticles serve as transducer for converting near-infrared light to shorter wavelength radiation. The unique optical properties of upconversion-luminescent nanoparticles make them promising candidates for a new class of luminescence probe in widespread applications such as luminescent labeling, displays, bioimaging, bioassays, drug delivery, sensors, and anticounterfeiting. In each field, polymers play an irreplaceable role and have been proven to be very useful from synthesis to surface modifications and further functionalization for upconversion-luminescent nanoparticles. Therefore, this article will focus on upconversion-luminescent nanoparticles/polymer nanohybrids and their new interesting fruits in applications.
- Recent Advances in Gas Barrier Thin Films via Layer-by-Layer Assembly of Polymers and Platelets
Morgan A. Priolo, Kevin M. Holder, Tyler Guin and Jaime C. Grunlan
Article first published online: 19 MAR 2015 | DOI: 10.1002/marc.201500055
This Feature Article reviews multilayer thin films, deposited layer-by-layer to produce a ‘nanobrick wall’ structure that imparts high gas barrier to permeable polymer substrates. These transparent, water-based thin films exhibit a lower permeability than any other barrier thin film material.
- Polymer–Albumin Conjugate for the Facilitated Delivery of Macromolecular Platinum Drugs
Aydan Dag, Yanyan Jiang, Khairil Juhanni Abd Karim, Gene Hart-Smith, Wei Scarano and Martina H. Stenzel
Article first published online: 19 MAR 2015 | DOI: 10.1002/marc.201400576
Delivery of platinum drugs using macromolecular platinum complexes is already an established pathway. Conjugation of these macromolecular drugs to albumin results in the formation of core–shell nanoparticles. As a result, the delivery of these drugs into ovarian cancer cells is enhanced leading to significantly higher drug activity.
- Mussel-Inspired One-Pot Synthesis of a Fluorescent and Water-Soluble Polydopamine–Polyethyleneimine Copolymer
Chenxu Zhao, Fang Zuo, Zhijian Liao, Zhenli Qin, Sinan Du and Zhigang Zhao
Article first published online: 19 MAR 2015 | DOI: 10.1002/marc.201500021
Mussel-inspired one-pot copolymerization of dopamine and polyethyleneimine (PEI) yields a novel fluorescent macromolecule, polydopamine-polyethyleneimine (PDA–PEI). The fluorescence property of PDA–PEI is mainly attributed to the Michael addition of PEI at the 5,6-dihydroxyindole unit of PDA. This work may facilitate the discovery of new strategies for controlling the emission characteristics of the PDA polymer.
