Claim:
A crosslinked polymer comprising a plurality of linear backbones and one or more crosslinking groups; wherein the crosslinking group comprises the formula: *—(SiR 2 —O) r —SiX 2 —(O—SiR 2 ) r —* wherein *— represents a bond between the crosslinking group and the backbone; wherein each X is independently selected from the group consisting of —R′, —(O—SiR 2 ) r —H, and —(O—SiR 2 ) r —*; wherein each R and each R′ is independently selected from the group consisting of alkyl, aryl, alkylaryl, haloalkyl, haloaryl, and mixtures thereof; and wherein each r is an independently selected integer greater than or equal to 1; and wherein the backbone comprises more than one of each of the groups —(C≡C) m —, —C b —, and —SiR 2 —(O—SiR 2 ) n —; wherein C b is a carboranyl group; wherein each m and each n is an independently selected integer greater than or equal to 1; wherein (C≡C) m represents a chain of m acetylene or acetylene-derived groups, each independently selected from the group consisting of
