Ruthenium polypyridine complexes as sensitizers in NiO based p-type dye-sensitized solar cells: effects of the anchoring groups

03-03-2011 | Yann, Pellegrin , Loïc, Le Pleux , Errol, Blart , Adèle, Renaud , Benoit, Chavillon , ..., Journal of Photochemistry and Photobiology A: Chemistry, 2011

In this contribution, we investigate the photovoltaic performances of four ruthenium trisbipyridine complexes in NiO based dye-sensitized solar cells (DSSC). The four complexes differ by the nature of the anchoring groups, which are either carboxylic acids, or biscarbodithioic acids or catechol ...


pH-Tunable Oxidase-Like Activity of Cerium Oxide Nanoparticles Achieving Sensitive Fluorigenic Detection of Cancer Biomarkers at Neutral pH

03-03-2011 | Atul Asati; Charalambos Kaittanis; Santimukul Santra; J. Manuel Perez, Analytical Chemistry, 2011

The reliable and sensitive detection of cancer-specific biomarkers is important for the diagnosis and treatment of cancer. Hence, detection of these biomarkers has to be reliably and rapidly performed in diverse settings. A limitation of the conventional biomarker-screening method of ...


Surface‐enhanced Raman spectroscopy (SERS) on silver colloids for the identification of ancient textile dyes. Part II: pomegranate and sumac

01-03-2011 | Silvia Bruni, Vittoria Guglielmi, Federica Pozzi, Anna Maria Mercuri; Silvia Bruni; Vittoria Guglielmi; Federica Poz ..., Journal of Raman Spectroscopy, 2011

Abstract The effectiveness of surface‐enhanced Raman spectroscopy (SERS) spectrocsopy on Ag colloids has been successfully demonstrated for the identification of a yellow dye in two ancient wool threads found in the Royal Tumulus of In Aghelachem, Libyan Sahara, belonging to the Garamantian ...


Use of confocal fluorescence microscopy to compare different methods of modifying metal–organic framework (MOF) crystals with dyes

01-03-2011 | Mingyan Ma; Annika Gross; Denise Zacher; Antonio Pinto; Heshmat Noei; Yuemin Wang; Roland A. Fischer; Nils Metzler-Nolte, CrystEngComm, 2011

Mingyan Ma, Annika Gross, Denise Zacher, Antonio Pinto, Heshmat Noei, Yuemin Wang, Roland A. Fischer, Nils Metzler-Nolte (Communication from CrystEngComm) Mingyan Ma, CrystEngComm, 2011, DOI: 10.1039/c0ce00416b To cite this article before page numbers are assigned, use the DOI form of ...


Detection of PCR products amplified from DNA of epizootic pathogens using magnetic nanoparticles and SERS

01-03-2011 | Strelau, Katharina Konstanze; Brinker, Anja; Schnee, Christiane; Weber, Karina; Möller, Robert; Popp, Jürgen, Journal of Raman Spectroscopy, 2011

Abstract Here we present a novel approach using surface‐enhanced Raman scattering (SERS) spectroscopy for the sequence‐specific detection of DNA utilizing magnetic nanoparticles (MNPs) for the enrichment of the target molecules. To achieve fast and efficient binding of longer DNA strands, e.g. ...


FT‐Raman spectroscopy—a rapid and reliable quantification protocol for the determination of natural indigo dye in Polygonum tinctorium

01-03-2011 | Fiedler, Andrea; Baranska, Malgorzata; Schulz, Hartwig, Journal of Raman Spectroscopy, 2011

Abstract In the recent years, Raman and IR spectroscopies have attracted increasing attention as fast, non‐invasive and widely applicable alternative analytical approaches for a variety of materials. Vibrational spectroscopy has been used in the analysis of herbal products, dyes and sensitive ...


Shape‐Persistent Macrocycles as Ligands and Sensitisers of Nd3+ Ions

01-03-2011 | Gallina, Maria Elena; Giansante, Carlo; Ceroni, Paola; Venturi, Margherita; Sakamoto, Junji; Schlüter, A. Dieter, European Journal of Inorganic Chemistry, 2011

Abstract Two shape‐persistent macrocycles with a hexagonal backbone incorporating two bpy units and two nonchromophoric methoxytetrahydropyran units (M), or two coumarin 2 dyes (C2–M–C2) are highly absorbing and emitting species in dichloromethane solution (ϵmax = 1.90 × 105M–1 cm–1 at 308 nm ...


Synthesis and Characterization of Near‐Infrared Absorbing Benzannulated Aza‐BODIPY Dyes

01-03-2011 | Gresser, Roland; Hummert, Markus; Hartmann, Horst; Leo, Karl; Riede, Moritz, Chemistry - A European Journal, 2011

Abstract A series of novel aza‐diisoindolmethine dyes 9 with six different aryl and heteroaryl groups at the indole moiety have been synthesized by the addition of aryl Grignard compounds to phthalodinitrile and subsequent reaction with formamide. A plausible reaction mechanism, through a ...


Synthesis and Spectral Properties of Novel Water‐soluble Indocyanine Dyes as Fluorescent Dyes for Proteins Detection

01-03-2011 | Fu, Yile; Wang, Lanying; Zhang, Xianghan; Lu, Tianqin; Xie, Qianjie; Shi, Zhen, Chinese Journal of Chemistry, 2011

Abstract Two novel water‐soluble indocyanine dyes were synthesized. Their chemical structures were confirmed by 1H NMR, IR, MS and UV‐vis techniques. The absorptions of the prepared dyes in different solvents were measured. Two dyes exhibited negative solvatochromism, with a blue shift of the ...


Dioxaborine- and Indole-Terminated Polymethines: Effects of Bridge Substitution on Absorption Spectra and Third-Order Polarizabilities

01-03-2011 | Jonathan D. Matichak; Joel M. Hales; Stephen Barlow; Joseph W. Perry; Seth R. Marder, Journal of Physical Chemistry A, 2011

Cyanine-like dyes are promising candidates for third-order nonlinear optical (NLO) applications such as all-optical switching. Here, we examine the consequences for linear and nonlinear optical properties of varying substituents on the central methine unit of bis(dioxaborine)-terminated anionic ...
