- Electrochemically Induced Synthesis of Poly(2,6-carbazole)
Katarzyna Laba, Przemyslaw Data, Pawel Zassowski, Krzysztof Karon, Mieczyslaw Lapkowski, Pawel Wagner, David L. Officer and Gordon G. Wallace
Article first published online: 28 JUL 2015 | DOI: 10.1002/marc.201500260
The formation of a poly(2,6-carbazole) derivative by electropolymerization is presented. Electrochemical and UV–Vis--NIR spectroelectrochemical measurements are shown. Electrochemical and spectroelectrochemical results are supported by density functional theory (DFT) calculation. Both of the compounds form stable and electroactive conjugated polymers. A problem that may be encountered by many researchers is presented.
- Facile and Quantitative Synthesis of a Poly(ethylene glycol)-b-Poly(l-arginine) Block Copolymer and Its Use for the Preparation of Polyion Complex Micelles with Polyanions for Biomedical Applications

The synthesis of poly(ethylene glycol)-block-poly(l-arginine) (PEG-b-PArg) is developed by a new method, i.e., the synthesis of PEG-b-poly(l-ornithine) (PEG-b-POrn) via ring-opening polymerization of the corresponding NCA, followed by effective guanidinylation. The polyion complex micelles composed of PEG-b-PArg and chondroitin sulfate C (CS) show a higher stability than those of PEG-b-POrn and CS against ionic strength, polyanion exchange, and FBS.
- Rational Design of Cancer-Targeted Benzoselenadiazole by RGD Peptide Functionalization for Cancer Theranostics
Liye Yang, Wenying Li, Yanyu Huang, Yangliang Zhou and Tianfeng Chen
Article first published online: 23 JUL 2015 | DOI: 10.1002/marc.201500243
A novel cancer-targeted prodrug BSeC-PEI-RGD with RGD peptide-conjugated selenocompound BSeC using PEI polymer as a linker is rationally designed and synthesized. BSeC-PEI-RGD shows selective cytotoxicity against cancer cells through induction of apoptosis with the involvement of intrinsic and extrinsic pathways. Moreover, the green fluorescence of BSeC-PEI-RGD supports its application potential in cancer diagnosis.
- A Combinatorial Photocrosslinking Method for the Preparation of Porous Structures with Widely Differing Properties
Erwin Zant, Maarten M. Blokzijl and Dirk W. Grijpma

Ethylene carbonate is a benign, water-soluble compound with a low melting point. Making combinatorial mixtures of macromers in solution in ethylene carbonate, subsequent photocrosslinking, and extraction with water allow us to simultaneously prepare large numbers of porous structures with a very wide range of physical properties. The figure illustrates a library of structures prepared in this manner.
