Chemical Equation Presentation On display: A high-speed and high-quality passive-matrix electrochromic display (ECD) is constructed from a leuco dye and a TiO nanoporous electrode (see picture). The vertical pores prevent the drifting of the colored dye molecules, leading to a clear image at high driving speeds. With full-color features, this kind of ECD promises to be a competitive candidate for a reflective electric display.

(Chemical Equation Presented) Rock 'n' roll cyaphide: Although the kinetic product B is an observable intermediate of nucleophilic attack on the low-coordinate phosphorus atom in A, it is not directly involved in the mechanism leading to cyaphide complex F. Instead, DFT calculations suggest that nucleophilic attack at silicon (→C) initiates decomposition via D to F. In contrast to cyanide complexes, isocyaphide E is only a transition state for C≡P-ligand rotation D⇌D′. © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.

The cap fits! A new class of concave π-extended tetrathiafulvalene (TTF) derivatives, truxene-TTFs, were prepared and characterized, and their self-assembly with fullerenes was investigated (see picture). Truxene-TTFs represent the first example of TTF-related electron donors that serve, without chemical modification, as monotopic receptors for fullerenes in solution.

(Chemical Equation Presented) Not just a pretty oxidant! IBX (1-Hydroxy-1,2-benziodoxol-3(1H)-on-1-oxide), an important oxidant in organic synthesis, is shown to be relatively acidic on the organic scale. The pK value and proton affinity of IBX were determined both in silico and in vitro. This acidity could explain the non-oxidation processes mediated by IBX.

Double your pleasure: A new double-tagging approach is validated by making eight individual stereoisomers of passifloricin through the intermediacy of a pair of four-compound quasi-isomeric mixtures. (Chemical Equation Presented) © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.

(Chemical Equation Presented) Stable and semiconducting: Polyanionic hydrides represent a new class of main-group-metal hydrides with unforeseen hydrogen-coordination environments. The hydrogen atom in SrAlSiH is attached exclusively to Al and forms part of a layered [AlHSi]2- polyanion (see figure). This material is the first narrow bandgap semiconductor hydride and combines the high thermal stability of saline hydrides with the air and moisture stability of interstitial transition-metal hydrides.

(Chemical Equation Presented) A disturbance in the library: The nitroaldol (Henry) reaction was developed as an efficient C-C bond-forming route to dynamic combinatorial libraries (DCLs). These DCL ...
