Pyrene-directed growth of nanoporous benzimidazole-linked nanofibers and their application to selective CO2 capture and separation

15-11-2012 | Mohammad Gulam Rabbani; Ali Kemal Sekizkardes; Oussama M. El-Kadri; Bilal R. Kaafarani; Hani M. El-Kaderi, Journal of Materials Chemistry, 2012

A pyrene-based benzimidazole-linked polymer (BILP-10) has been synthesized by the co-condensation of 1,3,6,8-tetrakis(4-formylphenyl)pyrene and 1,2,4,5-benzenetetramine tetrahydrochloride in dimethylformamide. The use of pyrene as a molecular building unit leads to the formation of self-assembled ...

Large-scale patterning by the roll-based evaporation-induced self-assembly

25-10-2012 | Won Kyu Park; TaeYoung Kim; Hyeongkeun Kim; Yena Kim; Tran Thanh Tung; Zhiqun Lin; A-Rang Jang; Hyeon Suk Shin; Jong ..., Journal of Materials Chemistry, 2012

The large-scale fabrication of highly regular polymer stripes was achieved either on rigid or flexible substrates via the roll-based evaporation-induced self-assembly (EISA) method. A control of stripe size was rendered by an adjustment of the jig speed and the polymer concentration. Large-scale ...

Highly ordered and gap controllable two-dimensional non-close-packed colloidal crystals and plasmonic–photonic crystals with enhanced optical transmission

17-10-2012 | Zhongyu Cai; Yan Jun Liu; Eunice S. P. Leong; Jinghua Teng; Xianmao Lu, Journal of Materials Chemistry, 2012

We present a facile one-step co-self-assembly method for the fabrication of two-dimensional (2D) non-close-packed (ncp) colloidal crystals (CCs) using polystyrene (PS) colloidal spheres and tetraethylorthosilicate (TEOS) sol. The resultant 2D ncp CCs demonstrated long-range ordering at the ...

A facile preparation of targetable pH-sensitive polymeric nanocarriers encapsulated magnetic nanoparticles for controlled drug release

16-10-2012 | Shun Yang; Dongyun Chen; Najun Li; Xiao Mei; Xiuxiu Qi; Hua Li; Qingfeng Xu; Jian-Mei Lu, Journal of Materials Chemistry, 2012

Novel multifunctional nanocomposites for controlled release of anti-cancer drug and magnetic resonance imaging (MRI) were successfully prepared via a simple self-assembly process. In this strategy, superparamagnetic iron oxide nanoparticles (SPIONPs) were “fixed” between the hydrophobic segment ...

Hairy Polymer Nanofibers via Self-assembly of Block Copolymers

10-10-2012 | Bhanu Nandan; Manfred Stamm; Andriy Horechyy; Hsin-Lung Chen; Rajiv Srivastava; Jit Pal; Sunita Sanwaria, Journal of Materials Chemistry, 2012

We demonstrate a simple approach to prepare hairy polymer nanorods/nanofibres by exploiting the self-assembly behavior of block copolymers. The hairy nanofibres were prepared from an asymmetric polystyrene-block-poly(4-vinylpyridine) (PS-b-P4VP) block copolymer whose self-assembled morphology ...

Core-crosslinked Amphiphilic Biodegradable Copolymer based on the Complementary Multiple Hydrogen Bonds of Nucleobases: Synthesis, Self-assembly and in vitro Drug Delivery

10-10-2012 | Huihui Kuang; Suhong Wu; Fanbo Meng; Zhigang Xie; Xiabin Jing; Yubin Huang, Journal of Materials Chemistry, 2012

Nucleobases (adenine and thymine) were conjugated to the amphiphilic biodegradable copolymers methoxyl poly(ethylene glycol)-b-poly(L-lactide-co-2-methyl-2-allyloxycarbonyl-propylene carbonate) (mPEG-b-P(LA-co-MAC)). The hydrogen bonding between adenine (A) and thymine (T) were confirmed by 1H ...

Boronate self-assembles with embedded Au nanoparticles; preparation, characterization and their catalytic activities for the reduction of nitroaromatic compounds

04-10-2012 | Yusuke Matsushima; Ryuhei Nishiyabu; Naoto Takanashi; Masatake Haruta; Hideaki Kimura; Yuji Kubo, Journal of Materials Chemistry, 2012

Sequential boronate esterification of benzene-1,4-diboronic acid with pentaerythritol induced hierarchical molecular self-assembly to produce mono-dispersed flower-like microparticles. ATR-FT-IR, PXRD, 13C-CP-MAS and 11B-DD-MAS NMR spectra indicate that the particles consist of zigzag-shaped ...

Thione–gold nanoparticles interactions: Vroman-like effect, self-assembly and sensing

04-10-2012 | Abilash Gangula; Janardhana Chelli; Santosh Bukka; Vivek Poonthiyil; Ramakrishna Podila; Raghuraman Kannan; Apparao ..., Journal of Materials Chemistry, 2012

The chemistry and interaction of thiones towards passivation, and self-assembly of metal nanoparticles is nascent and poorly understood. Here, we describe a sensitive (15 ppb) and rapid ...

Two Dimensional Directed [small pi]-[small pi] Interactions in A Linear Shaped Bi-1,3,4-oxadiazole Derivative to Achieve Organic Single Crystal with Highly Polarized Fluorescence and Amplified Spontaneous Emissions

04-10-2012 | Songnan Qu; Qipeng Lu; Shaohang Wu; Lijun Wang; Xingyuan Liu, Journal of Materials Chemistry, 2012

We reported the role of the molecular structure and molecular interactions of linear shaped bi-1,3,4-oxadiazole derivatives (BOXD-n) on their self-assembly behaviors and optical properties. The terminal chains of BOXD-n (n=1, 4) played an important role in molecular self-assembling and their ...

Oleamide as a self-assembled cathode buffer layer for polymer solar cells: the role of the terminal group on the function of the surfactant

03-10-2012 | Wenfeng Zhang; Haitao Wang; Boxue Chen; Xianghong Bi; Swami Venkatesan; Qiquan Qiao; Shangfeng Yang, Journal of Materials Chemistry, 2012

Amphiphilic surfactant oleamide was incorporated into P3HT:PCBM bulk heterojunction polymer solar cells (BHJ-PSCs) as a novel cathode buffer layer (CBL) for the first time by doping in the P3HT:PCBM photoactive layer followed by self-assembly. The power conversion efficiency (PCE) of the annealed ...
