Polymers of structure -[-CCSi(MeOctⁿ)CC-Z-]-_n(Z = 1,4-benzene, 4,4′-biphenyl, 9,10-anthracene, 2,7-fluorene, 2,5 and 2,6-pyridine, 6,6′-bipyridine, 2,5-thiophene, 2,6-p-dimethylaminonitrobenzene, 2,6-p-nitroaniline, 2,7-fluoren-9-one, p-tetrafluorobenzene, 2,6-p-nitrophenol or 2,6-p-cyanophenol) were prepared by reaction of diethynylmethyl(n-octyl)silane with the appropriate hetero(aromatic) dibromide or diiodide in the presence of (PPh₃)₂PdCl₂ and CuI. The polymer where Z = 6,6′-bipyridine reacted with copper(II) trifluoromethanesulfonate to give a copper(II)-containing polymer, reduction of which with hydrazine afforded the Cu(I)-containing polymer. The effect of change in reaction conditions on the cross-coupling polymerization was investigated. High mol. weights are favored by use of: (a) the diiodo- rather than the dibromoarene, (b) an equimolar mixture of the reactants or excess diethynylsilane, and in most cases (c) toluene cosolvent. The mol. weight passes through a maximum as the total catalyst concentration is increased, or as the individual Cu and Pd catalyst concentrations are sep. raised. The presence of tetraethylammonium chloride or high concentrations of triphenylphosphine reduces the mol. weight

Feng, Yan published the artcilePreparation and Capacity-Fading Investigation of Polymer-Derived Silicon Carbonitride Anode for Lithium-Ion Battery, COA of Formula: C9H20Cl2Si, the publication is ACS Omega (2017), 2(11), 8075-8085, database is CAplus and MEDLINE.

Polymer-derived silicon carbonitride (SiCN) materials have been synthesized via pyrolyzing from five poly(silylcarbondiimide)s with different contents of carbon (labeled as 1-5#). The morphol. and structure measurements show the SiCN materials are the mixtures of nanocrystals of SiC, Si3N4, and graphite. The SiCN materials have been used as anodes for lithium ion batteries (LIBs). Among the five polymer-derived SiCN materials, the 5#SiCN derived from dichloromethylvinylsilane and di-n-octyldichlorosilane, has the best cycle stability and high-rate performance at the low cut-off voltage of 0.01-1.0 V. In lithium-ion half-cells, the specific delithiation capacity of that 5#SiCN anode still remains at 826.7 mAh g-1 after 100 charge/discharge cycles; it can even deliver the capacity above 550 mAh g-1 at high current densities of 1.6 and 2 A g-1. In lithium-ion full cells, the 5#SiCN anode works well with NCM com. cathode. The outstanding electrochem. performance of 5#SiCN anode is attributed to two factors: (1) the formation of stable and compact SEI layer on the anode surface anode, which protects the electrode cracking during the charge/discharge cycling; (2) a large amount of carbon component the less Si3N4 phase in the 5#SiCN structure, which provides electrochem. reactive and conductive environment in the SiCN structure, benefits the lithiation/delithiation process. In addition, we explore the reason for the capacity fading of these SiCN anodes.

Cossement, D. published the artcileSelf-assembled monolayers of branched alkylsilanes on polycrystalline titanium surfaces, Name: Dichloro(methyl)(octyl)silane, the publication is Surface and Interface Analysis (2000), 30(1), 56-60, database is CAplus.

The silanization reaction on polycrystalline Ti surfaces was studied from the point of view of engineering a densely packed chemisorbed layer at the interface. For this purpose methyl-n-octyldichlorosilane (MODCS) and 2-methyl-1-trichlorosilylundecane (2MTCSU) were used and compared with n-octyltrichlorosilane (OTCS). XPS and contact angle measurements reveal that 2MTCSU forms well covering but not so densely packed monolayers as does OTCS. In contrast to 2MTCSU, MODCS does not provide a proper modification of the surface because of the small amount of mols. chemisorbed on the surface.

Kinetics of controlled simultaneous copolymerization of hexamethylcyclotrisiloxane (D₃) with functional cyclotrisiloxanes was studied using n-BuLi in THF as initiator. Trifunctional (MeXSiO)₃ (X₃), where X = vinyl, trifluoropropyl or chloropropyl group, and monofunctional monomers [(Me₂SiO)₂MeXSiO] (D₂X), where X = cyanopropyl or n-octyl group, were used as monomers. Reactivity ratios for each pair of comonomers were determined and the possibility of synthesis of gradient copolymers by this method is discussed.
