Preparation and Functions of Hybrid Membranes with Rings of Ag NPs Anchored at the Edges of Highly Ordered Honeycomb‐Patterned Pores

12-Aug-2013 | Renhao Dong, Jiaheng Xu, Zhefei Yang, Guangcheng Wei, Wenrong Zhao, Junlin Yan, Yu Fang, Jingcheng Hao, Chemistry - A European Journal, 2013

Abstract We report a new, simple strategy to apply honeycomb films for the patterning of colloidal particles. By combination of a “bottom‐up” breath figure method and the electrochemical properties of the honeycomb films of ferrocenyl‐based oligomers, highly ordered hybrid membranes coated ...

Tuning Dye-to-Particle Interactions toward Luminescent Gold Nanostars

12-Aug-2013 | Julien R.G. Navarro; Adrien Liotta; Anne-Charlotte Faure; Frederic Lerouge; Frederic Chaput; Guillaume Micouin; Patr ..., Langmuir, 2013

Light-matter interactions are of great interest for potential biological applications (bioimaging, biosensing, phototherapy). For such applications, sharp nanostructures exhibit interesting features since their extinction bands (surface plasmon resonance) cover a large bandwidth in the whole ...

Wavelength-Tunable Spasing in the Visible

09-Aug-2013 | Xiangeng Meng; Alexander V. Kildishev; Koji Fujita; Katsuhisa Tanaka; Vladimir M. Shalaev, Nano Letters, 2013

A SPASER, short for surface plasmon amplification by stimulated emission of radiation, is key to accessing coherent optical fields at the nanoscale. Nevertheless, the realization of a SPASER in the visible range still remains a great challenge because of strong dissipative losses. Here, we ...

Efficient Dye‐Sensitized Solar Cells Using a Tetramethylthiourea Redox Mediator

08-Aug-2013 | Yeru Liu, James R. Jennings, Qing Wang, ChemSusChem, 2013

Abstract An organic redox couple tetramethylthiourea/tetramethylformaminium disulfide (TMTU/TMFDS2+) is evaluated in dye‐sensitized solar cells in conjunction with a series of indoline and ruthenium‐based dyes. Of these, devices with indoline dye D205 show the best performance, with an ...

Biocompatible Pillararene-Assembly-Based Carriers for Dual Bioimaging

08-Aug-2013 | Huacheng Zhang; Xing Ma; Kim Truc Nguyen; Yanli Zhao, ACS Nano, 2013

Present research provides a successful example to use biocompatible pillararene-based assemblies for delivering mixed dyes in dual bioimaging. A series of tadpole-like and bola amphiphilic pillararenes 1–4 were synthesized by selectively employing water-soluble ethylene glycols and hydrophobic ...

A Simple Synthetic Route to Obtain Pure Trans‐Ruthenium(II) Complexes for Dye‐Sensitized Solar Cell Applications

07-Aug-2013 | Claudia Barolo, Jun‐Ho Yum, Emma Artuso, Nadia Barbero, Davide Di Censo, Maria Grazia Lobello, Simona Fantacci, Fili ..., ChemSusChem, 2013

Abstract We report a facile synthetic route to obtain functionalized quaterpyridine ligand and its trans‐dithiocyanato ruthenium complex, based on a microwave‐assisted procedure. The ruthenium complex has been purified using a silica chromatographic column by protecting carboxylic acid groups ...

Photochemical properties of squarylium cyanine dyes

07-Aug-2013 | Diana Pereira Ferreira; David Soares Conceição; Vania Graça; Vanessa Ferreira; Paulo Santos; L F Vieira Ferreira, Photochemical & Photobiological Sciences, 2013

This study presents several new squarylium dyes derived from benzothiazole and benzoselenazole with several structural variations, namely the nature of the heteroaromatic ring and the length of the N, N´-dialkyl groups. Before being investigated in connection with their effect on living cells ...

Assessing the guest-accessible volume in MOF by two-photon fluorescence microscopy

07-Aug-2013 | Nakcheol Jeong; Sung Min Shin; Mi Sun Lee; Ji Hee Han, Chemical Communication, 2013

The assessment of guest-accessible volume in MOF can reliably be done by using two-photon confocal fluorescence microscopy (TPM) with a tool-box of dyes ranging wide scope of size. It would be applicable to any porous materials, whose single-crystal structures are not available, or ...

Determination of the dye‐fixing mechanism of poly(dimethyldiallylammonium chloride)s on cotton fabric

05-Aug-2013 | Yikai Yu, Yuejun Zhang, Journal of Vinyl and Additive Technology, 2013

The dye‐fixing mechanism on cotton fabric of poly(dimethyldiallylammonium chloride)s (PDMDAACs) was determined in detail by using several chemical and physical techniques, in order to achieve clear new theoretical guidelines for the wide application of these dyefixatives to different dyes. ...
