Tunable parallel-plate capacitors employing Bi(1.5)Zn(1.0)Nb(1.5)O(7)/Ba(0.5)Sr(0.5)TiO(3) (BZN/BST) thin films for RF applications are reported. The intermediate frequency measurements indicate that the BZN/BST-based varactors demonstrate large tunability of 39% at 40 V and high device quality factor of 300 at 1 MHz. The devices maintain quite low leakage… (More)
Photoirradiation of bis(bithienyl)acetylenes in the presence of iodine undergoes sequential electrophilic and photochemical cyclizations to produce tetrathienonaphthalenes (TTN) in one pot. The TTN framework is readily transformed into cruciform π-extended derivatives, which form ordered nano/microstructures.
The title compound, [FeRu(C(5)H(5))(C(2)N(3))(C(17)H(14)P)(2)], was obtained by reaction of Cp(dppf)RuCl [dppf = 1,1'-bis-(diphenyl-phosphan-yl)ferrocene] with sodium dicyanamide in dichloro-methane. The Ru(II) atom is capped by an η(5)-cyclo-penta-dienyl (Cp) ring, a chelating dppf and a terminal C(2)N(3) unit, giving three-legged piano-stool geometry. The… (More)
The title compound, C58H64S8, has been prepared by Pd-catalysed direct C-H arylation of tetrathienonaphthalene (TTN) with 5-hexyl-2-iodothiophene and recrystallized by slow evaporation from dichloromethane. The crystal structure shows a completely planar geometry of the TTN core, crystallizing in the monoclinic space group P2(1)/c. The structure consists of… (More)
