Abstract

In this study, the precise positioning and alignment of arrays of two different guest molecules in a crystalline host matrix has been engineered and resulted in new optically active materials. Sub‐nm differences in the diameters of two types of 1D channels are sufficient for size‐selective inclusion of dyes. Energy transport occurs between the arrays of different dyes that are included in parallel‐positioned nanochannels by Förster resonance energy transfer (FRET). The color of individual micro‐sized crystals are dependent on their relative position under polarized light. This angular‐dependent behavior is a result of the geometrically constrained orientation of the dyes by the crystallographic packing of the host matrix and is concentration dependent.

Abstract

Several pyrrole-pyridin-based dibranched, heterocyclic 'push-pull' chromophore systems are synthesized and characterized. NMR and optical spectroscopy define the molecular structures and other physiochemical properties of chromophore monolayers and thin-film characterization emphasizes the importance of the chromophore molecular structure and film growth method on film microstructure and optical/electrooptic response.

24. Formation of difluoromethylene-arenium complexes by consecutive aryl-CF3 C-C bond activation and C-F bond cleavage

Abstract

A study on the activation of C-C and C-F bonds through the insertion of platinum group metal complexes in solution reports on the consecutive C-C activation and C-F cleavage in one chemical system. The process involves selective metal insertion into a very strong aryl-CF3 C-C bond followed by reaction of the resulting RhIII-CF3 complex with protonic or Lewis acids to form unique difluoromethylene-arenium complexes by C-F cleavage and C-C bond formation.

Abstract

Herein, two different functionalities of one metallo‐organic film assembled on the surface of a transparent metal‐oxide electrode are described. Two redox‐active elements, electrochromic iron–polypyridyl complexes and catalytically active palladium centers, operate by applying different potentials in aqueous solutions. The color of the material can be cycled 1500 times from dark purple to colorless by electrochemically addressing the Fe2+/3+ centers at 0.0–1.0 V (vs Ag/Ag+). The differences between the transmittance of these two states is high: ΔT = 52%. Catalytic water oxidation can occur by palladium oxide particles that form in situ by applying a higher potential (1.22–2.0 V vs Ag/Ag+), resulting in the formation of hydrogen and oxygen. The catalyst is active for at least 7 h in an aqueous electrolyte at pH = 6.9, with a Faradaic efficiency of ≈70%. [ABSTRACT FROM AUTHOR]

28. Unusual Surface Texture, Dimensions and Morphology Variations of Chiral and Single Crystals.

Abstract

We demonstrate here a unique metallo‐organic material where the appearance and the internal crystal structure are in contradiction. The egg‐shaped (ovoid) crystals have a brain‐like texture. Although these micro‐sized crystals are monodispersed; like fingerprints their grainy surfaces are never exactly alike. Remarkably, our X‐ray and electron diffraction studies unexpectedly revealed that these structures are single‐crystals comprising a continuous coordination network of two differently shaped homochiral channels. By using the same building blocks under different reaction conditions, a rare series of crystals have been obtained that are uniquely rounded in their shape. In stark contrast to the brain‐like crystals, these isostructural and monodispersed crystals have a comparatively smooth appearance. The sizes of these crystals vary by several orders of magnitude.

Abstract

Submolecular electrical information is successfully derived by applying element-specific, chemically resolved electrical measurements to a covalently bound stilbazole-based monolayer on a silicon substrate. The pronounced affinity effects are found in response of adjacent atomic sites to external charge injection, accompanied by intramolecular polarization variations.

Abstract

A hybrid structure consisting of a robust and structurally well-defined polypyridyl osmium complex and palladium precursor are constructed by using an iterative two-step assembly method. The studies have shown that the important characteristics of polyelectrolyte-based films and the molecular self-assembly (SA) are analogous, showing that the rich chemistry of surfaces engineered with molecular-based multilayers are extended to the functions of polyelectrolyte-based films.
