Leitfähige S-N-Polymere mit p-Phenylengruppen / Conductive S-N Polymers with p-Phenylen Groups

Abstract

<jats:p>Silylated diamines and diimines of type 13, 14 and 9-11 react with sulfur chlorine compounds SCl<jats:sub>2</jats:sub>, SOCl<jats:sub>2</jats:sub>, 8 and 12 to give 1-7 as linear S-N polymers with p-phenylen groups. Subsequent doping with acceptors (I<jats:sub>2</jats:sub>, Br<jats:sub>2</jats:sub>, AsF<jats:sub>5</jats:sub>) increases conductivity of 1-5 to ca. 10<jats:sup>-4</jats:sup>Ω<jats:sup>-1</jats:sup>cm<jats:sup>-1</jats:sup>.</jats:p>

BF3-Stabilized Metalated Sulfinylimides and Sulfurdiimides of the Type Cp(NO)2CrNSE·BF3 (E = O, NSiMe3)

“…CpCr(NO) 2 Cl, [21] Me 3 SiNSO [22] and S(NSiMe 3 ) 2 [23] were prepared according to literature procedures. X-ray Crystallography: Single crystals were selected and mounted with perfluoroether oil on the tip of a glass fiber.…”

Arsenic(III) and Antimony(III) Thionylimides

“…The organoarsenic and organoantimony com pounds PhAsCl2 [44], 'BuAsCU [45], 'BuSbCl2 [46], 'Bu2AsC1 [45] and 'Bu2SbCl [47] were prepared according to literature methods. Es tablished synthetic procedures are also available for the halfsandwich tricarbonyl metal-hydrides CpM (CO)3H (M = Cr, Mo, W [48]) and for the thionylimido compounds M e3SiNSO [23][24][25], KNSO [18,20] and Hg(NSO)2 [21].…”

“…We now report the synthesis and characterization of the homoleptic thionylimides As(NSO)3 and Sb(NSO)3, as well as some related organoarsenic and organoantim ony compounds containing thionylimide groups. [21] and the silyl com pound M e3SiNSO [22][23][24][25]. F or example, arsenic tri(thionylimide), As(NSO)3 (3 a), is accessible by several routes starting from the trihalides AsX3 (X = F, Cl, Br), according to the following equations:…”

Periodic-Orbit Theory

“…1). As the disks are moved closer together to form a bounded system, orbits disappear because of shading by one of the disks [61]. Nevertheless, one still seems to be able to label all trapped periodic orbits uniquely by a string of symbols.…”

“…The formal developments of the previous sections will now be applied to the three disk billiard [59,18,61,60,73]. This system is ideally suited to test the methods since a good symbolic dynamics is known and tuning of a parameter allows one to study the transition from an open strongly chaotic system to a bounded one.…”
