Abstract
A benzoxazine-bridged compound is provided. The compound has a low dielectric constant, a high mechanic strength and a high glass transition temperature. The compound has a highly cross-linked structure with a yellow-light photoluminescent emission. Characterization of the present disclosure has been conducted with Fourier transform infrared, nuclear magnetic resonance, molecular mass and elemental analysis.
