- Divergent Dendrimer Synthesis via the Passerini Three-Component Reaction and Olefin Cross-Metathesis
Oliver Kreye, Dennis Kugele, Lorenz Faust and Michael A. R. Meier
Article first published online: 6 DEC 2013 | DOI: 10.1002/marc.201300779
Divergent dendrimers of third generation, containing ester and amide functionalities, are synthesized using iterative steps of the Passerini three-component reaction with castor oil-derived platform chemicals, followed by olefin cross-metathesis with tert-butyl acrylate, hydrogenation, and hydrolysis.

The unique regular quadrangular prisms with the large microstructure are assembled on amorphous hyperbranched poly(methyl acrylate)-block-poly(acrylic acid) (HBPMA-b-PAA), which is mainly driven by a balance of contributions to the hydrogen bond interactions, the interfacial energy, and the repulsive interactions among unimolecular micelles. The formation of aggregates mainly depends on external pH-stimuli and the polymer concentration.
- Self-Assembled Microspheres Driven by Dipole-Dipole Interactions: UCST-Type Transition in Water
Nobuyuki Morimoto, Kanna Muramatsu, Tetsuichi Wazawa, Yuichi Inoue and Makoto Suzuki
Article first published online: 4 DEC 2013 | DOI: 10.1002/marc.201300798
Self-assembled microspheres based on dipole-dipole interactions are prepared using poly(ethylene glycol)-poly(sulfobetaine block copolymer. Microspheres are easy to obtain by dispersing the block polymer in water. The block copolymers exhibit an upper critical solution temperature (UCST) in water and the microspheres are dissociated above the UCST. The UCST increases when the degree of polymerization is increased.
- Combination of ATRA and ATRC for the Synthesis of Periodic Vinyl Copolymers
Chun-Hao Wang, Zi-Yuan Song, Xin-Xing Deng, Li-Jing Zhang, Fu-Sheng Du and Zi-Chen Li
Article first published online: 4 DEC 2013 | DOI: 10.1002/marc.201300721
A new approach to periodic vinyl copolymers is reported. The approach involves the synthesis of two MSUs via ATRA and the subsequent polymerization via ATRC, two new periodic copolymers of MMA and St, AN and St, are obtained and characterized.
- One-Pot Synthesis of Molecular Bottle-Brush Functionalized Single-Walled Carbon Nanotubes with Superior Dispersibility in Water
Yong Deng, Qin Hu, Qiulin Yuan, Yan Wu, Ying Ling and Haoyu Tang
Article first published online: 4 DEC 2013 | DOI: 10.1002/marc.201300673
Molecular bottle-brush functionalized single-walled carbon nanotubes (SWCNTs) with superior dispersibility in water are synthesized by a one-pot synthetic methodology. Elongating the main-chain and side-chain length of molecular bottle-brushes can further increase the SWCNT dispersibility.
