Abstract
A composition contains a mixture of silyl hydride, an alpha-beta unsaturated ester, a Lewis acid catalyst and an amine having the following formula: R1R2R3N; where the nitrogen is not a member of an N═C—N linkage and where each of R1, R2, and R3 is independently selected from a group consisting of hydrogen, alkyl, substituted alkyl, and conjugated moieties; and wherein at least one of R1, R2 and R3 is a conjugated moiety connected to the nitrogen by a conjugated carbon.
