Silicon-containing compound, composition containing said compound, and insulating material
View Patent ↗A composition for forming an insulating film comprising at least one of a compound represented by formula (1), a hydrolysate of the compound represented by formula (1) and a condensate of the compound represented by formula (1): A n SiX (4-n) (1) wherein n represents an integer of from 1 to 3; A represents an optionally substituted group containing a cage structure formed by 11 or more carbon atoms, and when n represents an integer of 2 or 3, A's are mutually same or different; and X represents a hydrolyzable group, and when n represents an integer of 1 or 2, X's are mutually same or different.
1. An insulating material formed by using a composition comprising:
(a) a compound represented by formula (3):
wherein (m31+m32+m33+m34) represents an integer of from 1 to 4;
n31 to n34 each independently represents an integer of from 1 to 3;
X 31 to X 34 each independently represents a hydrolyzable group;
R 31 to R 34 each independently represents an alkyl group, an aryl group or a heterocyclic group;
L 31 to L 34 each independently represents an alkylene, a vinylene, an arylene, —O—, —S—, —CO—, —NR′— or a divalent group including a combination thereof; and
R′ represents a hydrogen atom, an alkyl group or an aryl group;
(b) at least one of a hydrolysate of the compound represented by formula (3) and a condensate of the compound represented by formula (3); and
(c) at least one of an organic solvent and water.
2. An insulating film formed by using a composition according to claim 1 .
3. The insulating material according to claim 1 ,
wherein the hydrolyzable group represented by X 31 to X 34 is selected from the group consisting of a halogen atom, an alkoxy group, an aryloxy group, an acyloxy group, a silyloxy group and a hydroxyl group.
4. The insulating material according to claim 3 ,
wherein the hydrolyzable group represented by X 31 to X 34 is a substituted or unsubstituted alkoxy group.
5. The insulating material according to claim 1 ,
wherein R 31 to R 34 each independently represents a linear, branched or cyclic alkyl group, a substituted or unsubstituted phenyl group or naphthyl group, a substituted or unsubstituted hetero 6-membered ring or a substituted or unsubstituted hetero 5-membered ring.
