Different imaging modalities can provide complementary information on biological processes at the cellular or molecular level in vitro and in vivo. However, specific molecular probes suitable for a comparison of different imaging modalities are…
-
Association between cationic and anionic heptamethine dyes led to the formation of a new organic salt (3) displaying exceptional light-harvesting properties in the NIR spectral range and having amphoteric redox character. Preliminary results of…

The direct coupling reactions of 1,8-naphthalimide compounds efficiently occurred at 130 or 170 degrees C without the intervention of the leuco form dyes in the presence of base complex reagent, t-BuOK/1,5-diazabicyclo4.3.0non-5-ene (DBN), to give…

Co-crystal formation between caffeine and adipic acid has been explored over the years without success; utilizing the newly developed co-crystal screening method, we have finally discovered this "hidden" caffeine and adipic acid co-crystal.

Synonymous single-nucleotide polymorphisms (SNPs) do not produce altered coding sequences, and therefore they are not expected to change the function of the protein in which they occur. We report that a synonymous SNP in the Multidrug Resistance 1…

Reaction: see text Here we report a novel modification of our previously reported "Staudinger ligation" that generates an amide bond from an azide and a specifically functionalized phosphine. This method for the selective formation of an amide bond,…

A water-soluble turn-on fluorescent sensor for Hg(II) is described. Incorporation of soft thioether donors into an aniline-derived ligand framework that can be linked to a fluorescein platform affords sensor MS1, which shows a approximately 5-fold…
-
An architecture in which n- and p-type materials alternate laterally in the active film of a device with a spatial period of about a carrier diffusion length would lead to efficient (opto)electronic devices for photovoltaic energy conversion and…

A fluorescent probe selectively senses inorganic mercury in the turn-on mode through a mercury ion-promoted hydrolysis reaction that leads to a coumarin, among various other metal species except Au(III). (C) 2010 Elsevier Ltd. All rights reserved.

We present the first synthesis and characterization of a 1,3-dihydro-1,3-azaborine, a long-sought BN isostere of benzene. 1,3-Dihydro-1,3-azaborine is a stable structural motif with considerable aromatic character as evidenced by structural analysis…

A 10,000 member peptide nucleic acid (PNA) encoded peptide library was prepared, treated with the Abelson tyrosine kinase (Abl), and decoded using a DNA microarray and a fluorescently labeled secondary antiphosphotyrosine antibody. A dual-color…

RFID tags using organic transistors are described: Two 8b tags carrying different codes, energized and read out at 13.56MHz, the defacto standard for item-level ID, have been tested and demonstrated to enable multiple-object identification for the…
-
The primary metric for gauging progress in the various semiconductor integrated circuit technologies is the spacing, or pitch, between the most closely spaced wires within a dynamic random access memory (DRAM) circuit. Modern DRAM circuits have 140…
-
Solution NMR data can provide information about the interactions of molecules in the first stages of crystallisation, and 1H NMR complexation-induced changes in chemical shift can be used to determine high resolution three-dimensional structures of…

A 1°×1° resolution data set of historical anthropogenic trace gas emissions for the period 1890–1990An anthropogenic emissions data set has been constructed for CO2, CO, CH4, nonmethane volatile organic compounds, SO2, NOx, N2O, and NH3 spanning the period 18901990. The inventory is based on version 2.0 of the Emission Database for Global…

A new chiral glycine equivalent 7 has been synthesised from glycidol using a chiral memory protocol, and its use in the synthesis of N-Z protected alpha-amino acids was demonstrated in a series of diasteroselective lithium enolate alkylation…
-
A new type of ruthenium(II) complex containing a 2-quinolinecarboxylate ligand was designed and synthesized as a sensitizer for dye-sensitized solar cells, and its photophysical and photochemical properties were characterized. The solar cells…
-
Two-dimensional layered covalent organic frameworks (2D COFs) organize π-electron systems into ordered structures ideal for exciton and charge transport and exhibit permanent porosity available for subsequent functionalization. A 2D COF with the…
-
A method for predicting the binding mode of a series of ligands is proposed. The procedure relies on three-dimensional quantitative structure-activity relationships (3D-QSAR) and does not require structural knowledge of the binding site. Candidate…
