The modern theory of lipid membrane structure incorporates the concept lateral stress profile. latter represents forces that act on any solute inside membrane. We used this to propose two probes introduce minimal distortions into bilayer packing: surface pressure isotherms and volt-potentials pure mixed (probe-containing) monolayers are equal. represent a FRET pair. They applicable in transfer vesicle fusion experiments.
Cyclic silver( i ) fluorinated pyrazolates containing triphenylamine and carbazole moieties are emissive in solution the solid state, giving first example of silver pyrazolate adducts at room temperature.
Studies on copper(II) tetrafluorenyl porphyrinate (CuTFP) and tetraphenyl (CuTPP) have been focused the charge carrier transport in their solid films electroluminescence of composites. In dye layers deposited by resistive thermal evaporation, mobilities holes electrons are order 10-5 10-6 cm2 V-1 s-1 for under influence traps, mobility reaches 10-3 at space-charge-limited current nontrapping mode. For molecules, correlation between carriers distribution electron density highest occupied...
A series of emissive Cu(I) cationic complexes with 3-(2-pyridyl)-5-phenyl-pyrazole and various phosphines: dppbz (1), Xantphos (2), DPEPhos (3), PPh3 (4), BINAP (5) were designed characterized. Complexes obtained exhibit bright yellow-green emission (ca. 520-650 nm) in the solid state a wide range QYs (1-78%) lifetimes (19-119 µs) at 298 K. The photoluminescence efficiency dramatically depends on phosphine ligand type. theoretical calculations buried volumes excited states explained behavior...
Three new benzothiadiazole (BTD)-containing luminophores with different configurations of aryl linkers have been prepared via Pd-catalyzed cross-coupling Suzuki and Buchwald-Hartwig reactions. Photophysical electroluminescent properties the compounds were investigated to estimate their potential for optoelectronic applications. All synthesized structures sufficiently high quantum yields in film. The BTD bridged carbazole unit demonstrated highest electrons holes mobility a series. OLED...
A reaction of a cyclic trinuclear copper(I) or silver(I) pyrazolate complex ([MPz]3, M = Cu, Ag) with 1,1'-dimethyl-2,2'-bibenzimidazole (L) leads to the formation tetranuclear adducts decorated by one two molecules diimine ligand, depending on amount ligand added (0.75 1.5 equivalents). The coordination L stabilizes practically idealized tetrahedral four-metal core in case copper-containing and distorted tetrahedron Ag analog. In contrast, complexes containing molecule possess types metals,...
Polymer composites based on poly(N,N′-bis-4-butylphenyl-N,N′-bisphenyl)benzidine (poly-TPD) with PCBM and copper(II) pyropheophorbide derivative (Cu-PP) were developed. In thin films of the poly-TPD Cu-PP composites, charge carrier mobility was investigated for first time. ternary poly-TPD:PCBM:Cu-PP composite, electron hole mobilities are most balanced compared to binary photoconductivity is enhanced due sensitization by in blue red spectral ranges. The new promising use development photodetectors.

Archaeal lipids ensure unprecedented stability of archaea membranes in extreme environments. Here, we incorporate a characteristic structural feature an archaeal lipid, the cyclopentane ring, into hydrocarbon chains short-chain (C12) phosphatidylcholine to explore whether insertion would allow such lipid (1,2-di-(3-(3-hexylcyclopentyl)-propanoate)-sn-glycero-3-phosphatidylcholine, diC12cp-PC) form stable bilayers at room temperature. According fluorescence-based assays, water diC12cp-PC...
