Electrochemically controllable emission and coloration by using europium(III) complex and viologen derivatives.

We have demonstrated electroswitchable emission and coloration using a novel composite material containing luminescent europium(III) complex Eu(hfa)(3)(H(2)O)(2) and diheptyl viologen HV(2+). The photoluminescence of the Eu(III) complex was controlled by the electrochemical coloration of HV(2+)via intermolecular energy transfer mechanisms.

Unique assembly of low-dimensional viologen iodoplumbates and their improved semiconducting properties.

Two unique low-dimensional benzyl viologen iodoplumbates [Pb(13)I(38)][B'V](6) (1) and [(Pb(5)I(14))(BV)(2)](n) (2) were prepared from solvothermal reactions of benzyl alcohol with 4,4'-bipy, PbI(2), I(2) and a small amount of water in acetonitrile. The semiconducting properties of the single crystals 1 and 2 along with Zn/Cl-doped samples 2a and 2b were investigated.

Viologen-mediated assembly of and sensing with carboxylatopillar[5]arene-modified gold nanoparticles.

Carboxylatopillar[5]arene (CP[5]A), a new water-soluble macrocyclic synthetic receptor, has been employed as a stabilizing ligand for in situ preparation of gold nanoparticles (AuNPs) to gain new insights into supramolecular host-AuNP interactions. CP[5]A-modified AuNPs with good dispersion and narrow size distributions (3.1 ± 0.5 nm) were successfully produced in aqueous solution, suggesting a...

Chemically and electrochemically triggered assembly of viologen radicals: towards multiaddressable molecular switches.

We have established that bipyridinium radicals can be reversibly π-dimerized under the combined effects of chemical (proton transfer) and electrochemical (electron transfer) stimuli. Our investigations also led to the discovery that a bis-pyridinyl appended calixarene intermediate is involved in a fully reversible redox-triggered σ-dimerization process. The structure of the most stable intramol...

Solid-phase synthesis of peptide-viologen conjugates.

This paper presents a robust method for the conjugation of viologens to peptides using an amide coupling strategy that is compatible with standard Fmoc solid-phase peptide synthesis. Methodology is presented for monitoring the milligram scale process quantitatively by UV spectroscopy. This chemistry enables the synthesis of a broad range of asymmetric viologens in high yield at room temperature...
