Abstract
Official abstract text for this publication.
The present invention relates to compositions comprising at least one hydridosilane of the generic formula SinHm with n≥5 and m=(2n) and (2n+2) and at least one compound of the formula HnB (OR)3−n with R=C1-C10-alkyl, C6-C10-aryl, C7-C14-aralkyl, halogen, n=0, 1, 2, to processes for preparation thereof and use thereof.
First claim
Opening claim text (preview).
The invention claimed is: 1. A composition comprising: (i) at least one hydridosilane of formula Si n H m with n≥5 and m=(2n) to (2n+2), and (ii) at least one compound of formula H n B(OR) 3−n with R=C 1 -C 10 -alkyl, C 6 -C 10 -aryl, C 7 -C 14 -arylalkyl, or halogen, and n=0, 1, or 2. 2. The composition according to claim 1 , wherein the at least one hydridosilane is a hydridosilane oligomer prepared from a hydridosilane of formula Si x H 2x+2 with x≥3 or a cyclic hydridosilane of formula Si x H 2x with x≥5. 3. The composition according to claim 2 , wherein the hydridosilane oligomer is obtained via thermal oligomerization of a composition comprising, as hydridosilane, at least one hydridosilane of formula Si x H 2x+2 with x≥3-20 in the absence of a catalyst at a temperature of less than 235° C. 4. The composition according to claim 3 , wherein the hydridosilane of the formula Si x H 2x+2 is neopentasilane. 5. The composition according to claim 2 , wherein the hydridosilane of the formula Si x H 2x with x≥5 is cyclopentasilane. 6. The composition according to claim 1 , wherein the compound of the formula H n B(OR) 3−n has a formula H n B(OC 4 H 9 ) 3−n with n=1 or 2. 7. The composition according to claim 1 , further comprising at least one solvent. 8. The composition according to claim 3 , further comprising a hydridosilane of formula Si n H 2n+2 with n=5-9. 9. A process for preparing the composition according to claim 1 , comprising mixing the at least one hydridosilane, the at least one compound of the formula H n B(OR) 3−n and any further constituents.
