- Multicolor Luminescence from Conjugates of Genetically Encoded Elastin-like Polymers and Terpyridine-Lanthanides
Koushik Ghosh, Eva Rose M. Balog, Jennifer L. Kahn, Douglas P. Shepherd, Jennifer S. Martinez and Reginaldo C. Rocha
Article first published online: 20 AUG 2015 | DOI: 10.1002/macp.201500103
Photoluminescent metallo-biopolymers are assembled via a facile and versatile plug-and-play approach. Integration of terpyridine and then lanthanides into genetically encoded elastin-like polymers yields emitting platforms displaying an array of tunable luminescent colors across the visible and near-infrared regions. The demonstrated strategy for constructing such hybrid (bio)polymer assemblies provides a sustainable path toward functional optical (bio)materials.
- Synthesis, Morphology, and Properties of Polyurethane-triazoles by Click Chemistry

A series of novel linear polyurethane-triazoles (PUTs) are prepared using the in situ click reaction. The 1,4-disubstituted triazole groups are incorporated into the main chains of PUTs. Because of the extra dipole–dipole and hydrogen bonds of 1,4-disubstituted triazole rings in the hard segments, microphase separation of the PUTs is enhanced.
- Vanadyl-TrBR4-Catalyzed Oxidative Polymerization of Diphenyl Disulfide

Strong-acid-free oxygen-oxidative polymerization of PhSSPh is presented, catalyzed by a vanadyl and TrBR4 system. TrB(C6F5)4 is found to activate VO(acac)2 at 100 °C and the catalyst gives poly(1,4-phenylene sulfide) (PPS) from PhSSPh. TrBF4 has stronger nucleophilicity, but is found to activate VO(salen) and VO(TPP) at 160 °C for preparing PPS.
- Bioapplications of Polythiophene-g-Polyphenylalanine-Covered Surfaces

Thiophene-functionalized polyphenylalanine macromonomer is synthesized and used as polymerized form “Polythiophene-graft-polyphenylalanine” in electrochemical biosensing and cell adhesion applications. Initially, it is conducted to glucose sensing via glucose oxidase immobilization, and secondly the constructed surfaces on indium tin oxide within the modification of RGD peptide are used for the selective cell binding in the way of cell viability and electrochemical biosensing platform.
- Pullulan-Based Polymer Surfactants for Vinyl Acetate Miniemulsion Polymerization: Kinetics and Colloidal Stability Investigations
Sabrina Belbekhouche, Luc Picton, Didier Le Cerf and Thierry Hamaide
Article first published online: 19 AUG 2015 | DOI: 10.1002/macp.201500130
Pullulan-b-Jeffamine block copolymers are versatile bio-based polymer surfactants for an efficient stabilization of vinyl acetate miniemulsion polymerization. They enable a long-term colloidal stabilization, even in the presence of salts. Hydrophobic initiators are required in order to avoid possible reaction between incoming radicals and sugar units of the pullulan chain, which affects the kinetics and polymer average molecular weights.
