A π-Conjugated, Covalent Phosphinine Framework

Huang, Jieyang; Tarábek, Ján; Kulkarni, Ranjit; Wang, Cui; Dracínský, Martin; Smales, Glen J.; Tian, Yu; Ren, Shijie; Pauw, Brian R.; Resch-Genger, Ute; Bojdys, Michael J.

Structural modularity of polymer frameworks is a key advantage of covalent organic polymers, however, only C, N, O, Si, and S have found their way into their building blocks so far. Here, the toolbox available to polymer and materials chemists is expanded by one additional nonmetal, phosphorus. Starting with a…

Role of the Hydrophilic Latex Particle Surface in Water Diffusion into Films from Waterborne Polymer Colloids

Konko, Iuliia; Guriyanova, Svetlana; Boyko, Volodymyr; Sun, Lichao; Liu, Dong; Reck, Bernd; Men, Yongfeng

The diffusion mechanism and growth of large-scale domains during the immersion of latex films in water have been thoroughly investigated with scattering techniques in a combination with the gravimetric method. Latex dispersions for film formation studies had identical main monomer compositions and only differ in the hydrophilic comonomers that result…

Mechanistic understanding of monovalent cation transport in eumelanin pigments

Tian, Zhen; Hwang, Wonseok; Kim, Young Jo

Recent research advances in charge-conducting materials have enabled the transformation of the naturally-occurring materials into crucial components in many technologies, including renewable energy storage devices or bioelectronics. Among various candidates, eumelanins are promising charge storage materials, exhibiting hybrid electronic ionic conductivity in a hydrated environment. The chemical…

Mutually-complementary structure design towards highly stretchable elastomers with robust strength and autonomous self-healing property

Wu, Bo; Liu, Zhimeng; Lei, Yuan; Wang, Yi; Liu, Qinfeng; Yuan, Anqian; Zhao, Yuanyang; Zhang, Xi; Lei, Jingxin

Achieving good transparency, high strength and superior extensibility simultaneously in autonomic self-healing elastomers remains challenging and fascinating. Herein, a complementary design strategy of combining densely distributed multiple hydrogen bonds (H bonds) and loosely packed spacer units in supramolecular elastomer was reported to address the inherent contradiction of robust strength and…

Propyl–SO3H functionalized SBA-15: Microwave-mediated green synthesis of biologically active multi-substituted imidazole scaffolds

Gabla, Jenifer J.; Lathiya, Dharmesh R.; Revawala, Akash A.; Maheria, Kalpana C.

Propylsulfonic acid functionalized Santa Barbara Amorphous-15 (SBA-15–Pr–SO3H) catalyst has been synthesized using a surface modification of mesoporous SBA-15 via the one-pot co-condensation method. The synthesized SBA-15–Pr–SO3H has been characterized by peculiar characterization techniques such as small- and wide-angle XRD, SEM–EDX, TEM, TG–DTA, acidity, FT-IR, Py-FT-IR and BET surface area…

Self-assembly of a silicon-containing side-chain liquid crystalline block copolymer in bulk and in thin films: kinetic pathway of a cylinder to sphere transition

Liao, Fen; Shi, Ling-Ying; Cheng, Li-Chen; Lee, Sangho; Ran, Rong; Yager, Kevin G.; Ross, Caroline A.

The self-assembly of a high-? silicon-containing side-chain liquid crystalline block copolymer (LC BCP) in bulk and in thin films is reported, and the structural transition process from the hexagonally packed cylinder (HEX) to the body-centered cubic structure (BCC) in thin films was examined by both reciprocal and real space experimental…

Kinetics-controlled synthesis of hierarchically porous materials with tunable properties from diverse building blocks

Xie, Lei; Wang, Zhe; Liu, Jinrong; Gong, Yutong; Mao, Shanjun; Lü, Guofeng; Ma, Xiao; Yu, Lili; Wang, Yong

The easy hydrothermal method is a potential candidate for the preparation of carbohydrate-derived hierarchically porous polymers (HPPs) and carbons (HPCs). However, owing to the uncontrolled reaction rate and the weak affinity between precursors and soft templates, the synthesis of HPPs and HPCs with tunable properties through this method remains a…

Shape and phase controlled synthesis of mesostructured carbon single crystals through mesoscale self-assembly of reactive monomicelles and their unprecedented exfoliation into single-layered carbon nanoribbons

Wang, Tianping; Sun, Yanbin; Wu, Jiali; Liu, Xiangyang; Pan, Ruping; Liu, Xikui

The formation of mesostructured polymer and carbon single-crystals is very difficult due to increased complexity of the energy hypersurface and the role of slowed-down kinetics. Here we reported the synthesis of ordered mesostructured phloroglucinol-formaldehyde single crystals through mesoscale self-assembly of reactive monomicelles under acidic conditions which were traditionally thought very…

Unprecedented Halide-Ion Binding and Catalytic Activity of Nanoscale Anionic Metal Oxide Clusters

She, Shan; Li, Mu; Li, Qi; Huang, Zehuan; Wei, Yongge; Yin, Panchao

One halide ion (X?) can bind on the surface of nanoscale Anderson-type polyoxometalate (POMs) clusters 3AlMo6O18(OH)3, and form stable complexes in solution with binding constant K=1.53×103. Single-crystal structural analysis showed that this binding behavior occurs through multiple hydrogen bonding between X? and three hydroxy groups on the uncapped side of…

Identification of a Frank-Kasper Z phase from shape amphiphile self-assembly

Su, Zebin; Hsu, Chih-Hao; Gong, Zihao; Feng, Xueyan; Huang, Jiahao; Zhang, Ruimeng; Wang, Yu; Mao, Jialin; Wesdemiotis, Chrys; Li, Tao; Seifert, Soenke; Zhang, Wei; Aida, Takuzo; Huang, Mingjun; Cheng, Stephen Z. D.

Frank–Kasper phases, a family of ordered structures formed from particles with spherical motifs, are found in a host of materials, such as metal alloys, inorganic colloids and various types of soft matter. All the experimentally observed Frank–Kasper phases can be constructed from the basic units of three fundamental structures called…
