2,4 and 2,5-bis(benzooxazol-2[prime or minute]-yl)hydroquinone (DHBO) and their borate complexes: Synthesis and Optical properties

27-Apr-2016 | Karima Benelhadj; Julien Massue; Gilles Ulrich, New Journal of Chemistry, 2016

This article describes the multistep synthesis and the solution/solid-state optical properties of a series of highly fluorescent dyes based on either a 2,4 or a 2,5-bis(benzooxazol-2′-yl)hydroquinone (DHBO) scaffold. Their fluorescent emission stems from an intrinsic Excited-State Intramolecular ...

Non-covalent stacking interactions directing the structural and photophysical features of mono- and dinuclear cyclometalated palladium(II) complexes

27-Apr-2016 | M. Dolores Santana; Luisa López-Banet; Gregorio Sánchez; Jose Pérez; Eduardo Pérez; Luis García; JoseLuis Serrano; A ..., Dalton Transactions, 2016

The solution/solid state luminescence properties of selected orthometalated palladium complexes have been investigated in parallel with the relevant structural information provided by their X-ray crystal structures and theoretical calculations. Two cyclometallated backbones with different ...

Quantitative Analysis of Trace Palladium Contamination in Solution using Electrochemical X-Ray Fluorescence (EC-XRF)

27-Apr-2016 | Zoe J Ayres; Mark Edward Newton; Julie V Macpherson, Analyst, 2016

The application of electrochemical X-ray fluorescence (EC-XRF), for the detection of palladium (Pd) contamination in a range of solutions containing electrochemically active compounds, present in excess and relevant to the pharmaceutical and food industries, is reported. In EC-XRF, EC is used to ...

Au/TiO2 photocatalysts prepared by solid grinding for artificial solar-light water splitting

26-Apr-2016 | Valerie KELLER; Clément Marchal; Matthieu Behr; Valérie Caps; Fabrice Vigneron, New Journal of Chemistry, 2016

Here we show in an innovative way that solid grinding is a simple and alternative method for the preparation of solar-light active Au/TiO2 photocatalysts. We use, for the first time in the solid grinding method, triphenylphosphine gold (I) chloride (AuPPh3Cl), which has recently been used in ...

Microfluidic-based photocatalytic microreactor for environmental application: A review of fabrication substrates and techniques, and operating parameters

26-Apr-2016 | Susmita Das; Vimal Chandra Srivastava, Photochemical & Photobiological Sciences, 2016

Photochemical technology with microfluidic is emerging as new platform in environmental science. Microfluidic technology has various advantages like better mixing because of large surface to volume ratio and shorter diffusion distance of the reactant solution; and uniform distribution of light ...

Dioxygen-mediated oxidation of hydroquinone with cobalt ions in bicarbonate aqueous solution for the production of active radicals

26-Apr-2016 | Zhang Dajie; Shi Wei; Cheng Qiang; Li Xiaoxia; Aihua Xu, New Journal of Chemistry, 2016

The catalytic effect of Co2+ in HCO3- aqueous solution on the oxidative transformation of 1,4-hydroquinone (H2Q) to 1,4-benzoquinone (BQ) with molecular oxygen as the oxidant was investigated. The measured catalytic activity of Co2+-HCO3- was higher than Cu2+ and other ions, and the enhancement ...

Synthesis and Recognition Properties of Calix[4]arene Semitubes as Ditopic Hosts for N-alkyl-pyridinium Ion Pairs

26-Apr-2016 | Francesco Vita; Michela Vorti; Guido Orlandini; Valeria Zanichelli; Chiara Massera; Franco Ugozzoli; Arturo Arduini; ..., CrystEngComm, 2016

A series of calix[4]arene semitubes (4a-c) having alkyl bridging spacers of different length and flexibility on their lower rim was synthesised and characterised in solution and in the solid state by 1H NMR spectroscopy and X-ray crystallography. The binding properties of these novel ditopic ...

On-Resin Diels-Alder Reaction with Inverse Electron Demand: Efficient Ligation Method for Complex Peptides with Varying Spacer to Optimize Cell Adhesion

26-Apr-2016 | Mareen Pagel; René Meier; Klaus Braun; Manfred Wiessler; Annette G Beck-Sickinger, Organic & Biomolecular Chemistry, 2016

Solid phase peptide synthesis (SPPS) is the method of choice to produce peptides. Several protecting groups enable specific modifications. However, complex peptide conjugates usually require a rather demanding conjugation strategy, which is mostly performed in solution. Herein, an efficient ...

Functional Porous Composites by Blending with Solution-Processable Molecular Pores

26-Apr-2016 | Shan Jiang; Lin Chen; Michael E. Briggs; Tom Hasell; Andrew Cooper, Chemical Communication, 2016

We present a simple method for rendering non-porous materials porous by solution co-processing with organic cage molecules. This method can be used both for small functional molecules and for polymers, thus creating porous composites by molecular blending, rather than the traditional approach of ...

COOPERATIVE HYDROGEN-BONDING OF THE ADENINE-THYMINE PAIR AS A STRATEGY FOR LOWERING THE LIMIT OF DETECTION OF THYMINE BY SURFACE-ENHANCED RAMAN SPECTROSCOPY

26-Apr-2016 | Mónica Benicia Mamián-López; Paola Corio; Marcia Temperini, Analyst, 2016

The formation of cooperative hydrogen bonds between the thymine-adenine pair was used to indirectly determine thymine in aqueous solution by Surface-enhanced Raman Spectroscopy (SERS), therefore improving the limit of detection (LOD) values up to two orders of magnitude. The concentration of ...
