- Chelation-Induced Polymer Structural Hierarchy/Complexity in Water
Jie Han, Kaiyi Zhou, Xuechao Zhu, Qiuping Yu, Yi Ding, Xinhua Lu and Yuanli Cai

Nanoscale structural hierarchy and complexity of hydrophilic flexible polymers are available via copper chelation–induced self-assembly (CCISA) in water. Hierarchically ordered networks and disks have been achieved via supramolecular-to-supracolloidal stepwise-growth CCISA mechanism, simply by deliberate control of aliphatic spacer length and solution pH.
- Self-Assembly Directed Organization of Nanodiamond During Ionic Liquid Crystalline Polymer Formation
Bryan S. Ringstrand, Sönke Seifert, David W. Podlesak and Millicent A. Firestone
Version of Record online: 19 MAY 2016 | DOI: 10.1002/marc.201600070
Site localization of nanodiamond within the alkyl chain region of a 2D hexagonal nanostructured polymer is achieved by co-polymerization of a lyotropic mesophase composed of the ionic liquid monomer functionalized detonation diamond with the ionic monomer.
- Harnessing Poly(ionic liquid)s for Sensing Applications
Ryan Guterman, Martina Ambrogi and Jiayin Yuan

Poly(ionic liquid)-derived functional materials and devices for sensing applications have emerged as a new field that grows rapidly. Diversity in chemistry and physics of ionic liquids is nicely coupled with the excellent processability and multivalency of polymers, allowing for task-specific detection of solvents, gases, biomolecules, pH, and anions.
- Adjusting Local Molecular Environment for Giant Ambient Thermal Contraction
Xingyuan Shen, Timothy Connolly, Yuhui Huang, Michael Colvin, Changchun Wang and Jennifer Lu

A twofold enhancement of negative thermal expansion (NTE) coefficient has been achieved in a polymer system containing S-dibenzocyclooctadiene. Varying the degree of molecular structural randomness, tunable NTE has been attained. Experimental and theoretical analyses indicate that molecular randomness results in a loosely packed morphology and consequently facilitates the S-dibenzocyclooctadiene conformation change. These materials can be exploited for multiple applications.
- Fabrication of Dendrimer-Based Polyion Complex Submicrometer-Scaled Structures with Enhanced Stability under Physiological Conditions
Kenshiro Naoyama, Takeshi Mori, Yoshiki Katayama and Akihiro Kishimura
Version of Record online: 18 MAY 2016 | DOI: 10.1002/marc.201600171
Polyion complex (PIC) formation behaviors are carefully examined using a block aniomer, poly(ethylene glycol)-b-poly(aspartic acid), and homocatiomers, dendritic poly(l-lysine) with different generations, compared with PIC obtained from a linear-analog, poly(l-lysine). Dendritic architecture contributes to the stability enhancement of submicrometer-scaled self-assemblies under physiological salt and temperature conditions as well as structural control of the self-assemblies.
