Bismelamines end-functionalized with oligo(p-phenylenevinylene) self-aggregate in nonpolar solvent to form short nanorods by helical π-π stacking. This inherent self-aggregation can be guided to a supramolecular polymerization pathway by complexing with a cyanurate, leading to gel-forming ...

Incorporation of fluorous ponytails such as polyfluorinated alkyl residues (CH2)m(CF2)nCF3 leads to a novel class of bright rhodamine-based fluorescence dyes. These dyes combine the excellent photophysical properties of the frequently used rhodamine dyes with the unique features of “light” ...

Graphene-like BN nanosheets were synthesized via carbon-substitution reaction using graphene as a template in an attempt to produce C-doped BN. The carbon residue was removed by high-temperature oxidation in air. The role of the graphene template and oxygen with regard to the local structure ...

A revolutionary probe was constructed by conjugating Cy5 on a graphene oxide sheet. The fluorescence was quenched owing to its proximity to graphene oxide in normal circumstances, but lit on arriving at the tumor site. Both in vitro and in vivo studies demonstrated that the probe exhibits ...

Scanning tunneling microscopy images of diferrocenylacetylene (DFA) coadsorbed with benzene on Au(111) show individual and close-packed DFA molecules, either adsorbed alongside benzene or on top of a benzene monolayer. Images acquired over a range of positive and negative tip–sample bias ...

We report a study of the microstructural templating role of incipient fibrin–thrombin gels by analysis of rheological and confocal microscope measurements. Fractal analysis based on the spectral dimension is used, for the first time, to characterise fibrin gel microstructure in terms of the ...

Many but not all iron--sulphur clusters in metalloproteins are known to be sensitive to molecular oxygen with dramatic consequences for their biological function. We performed a systematic quantum chemical investigation that sheds light on the differences in oxygen sensitivity depending on ...

This article explores the extent to which insights gleaned from detailed studies of molecular photodissociations in the gas phase (i.e. under isolated molecule conditions) can inform our understanding of the corresponding photofragmentation processes in solution. Systems selected for ...
