New luminescent poly(methylmethacrylate) (PMMA) nanocomposites with high content of different hexanuclear octahedral cluster building blocks, namely [Mo6I8(C2F5COO6)](2-), [Re6Se8(CN)6](4-) and [W6Cl14](2-) have been prepared by free-radical polymerisation. To do so, cluster complexes bearing a polymerisable ammonium counter-cation have been synthesised....

PMID: 12935031
Phys Rev Lett. 2003 Aug 15;91(7):075502. doi: 10.1103/PhysRevLett.91.075502. Epub 2003 Aug 15.

We demonstrate that the statistical behavior of random line shapes of single tetra-tert-butylterrylene chromophores embedded in an amorphous polyisobutylene matrix at T=2 K is described by Lévy statistics as predicted theoretically by Barkai, Silbey, and Zumofen [Phys. Rev. Lett....

Multichannel liquid-crystal-based wave-front corrector with modal influence functions.

Optics letters

Naumov AF, Vdovin G.
PMID: 18091843
Opt Lett. 1998 Oct 01;23(19):1550-2. doi: 10.1364/ol.23.001550.

We report on a multichannel liquid-crystal-based wave-front corrector with smooth modal influence functions. The phase is controlled by application of spatially localized ac voltages to a distributed voltage divider formed by a liquid-crystal layer sandwiched between a high-conductance and...

Jørgensen complex within a molecular container: selective encapsulation of trans-[Co(en)2Cl2]+ into cucurbit[8]uril and influence of inclusion on guest's properties.

Inorganic chemistry

Mitkina TV, Sokolov MN, Naumov DY, Kuratieva NV, Gerasko OA, Fedin VP.
PMID: 16903754
Inorg Chem. 2006 Aug 21;45(17):6950-5. doi: 10.1021/ic060502z.

The unprecedented selective encapsulation of trans-[Co(en)2Cl2]+ from the mixture of trans and cis isomers into the cavity of macrocyclic cavitand cucurbit[8]uril (C48H48N32O16, CB[8]) leads to the inclusion compound {trans-[Co(en)2Cl2]@CB[8]}Cl.17H2O (1). Single-crystal X-ray analysis, 1H NMR, and ESI-MS spectra confirm...

V4S9Br4: a novel high-spin vanadium cluster thiobromide with square-planar metal core.

We present a technique for the measurement of the low-temperature fluorescence excitation spectra and imaging of a substantial fraction of all single chromophore molecules (hundreds of thousands and even more) embedded in solid bulk samples as nanometre-sized probes. An...

The conversions of hexahydroxo rhenium cluster complexes [Re6Q8(OH)6]4- (Q=S, Se) in aqueous solutions in a wide pH range were investigated by chemical methods and spectroscopic measurements. Dependences of the spectroscopic and excited-state properties of the solutions on pH have...

Cooperative response of Pb(ZrTi)O3 nanoparticles to curled electric fields.

Phys Rev Lett. 2008 Nov 07;101(19):197601. doi: 10.1103/PhysRevLett.101.197601. Epub 2008 Nov 04.

We investigate cooperative responses, as well as a microscopic mechanism for vortex switching, in Pb(Zr0.5Ti0.5)O3 nanoparticles under curled electric fields. We find that the domain coexistence mechanism is not valid for toroid switching. Instead dipoles display unusual collective behavior...
