Polymerizable Optical Compound Balancing Refractive Index and Solubility

The patent changes the molecular structure parameters by introducing fused aromatic ring substituents (naphthalene, anthracene, phenanthrene rings) onto the phenoxy core structure. This structural modification increases the refractive index while the specific arrangement and linking groups maintain solubility properties, resolving the trade-off between optical performance and solubility.

The patent creates a composite molecular structure combining a phenoxy core with multiple fused aromatic ring substituents linked through specific linking groups. This composite structure achieves high refractive index through the aromatic content while the linking groups and overall architecture maintain solubility, effectively resolving the contradiction between molecular weight increase and solubility maintenance.

The patent segments the molecular structure into distinct functional components: a phenoxy core, fused aromatic ring substituents for optical properties, and specific linking groups for solubility. This segmentation allows each component to fulfill its function independently, maintaining solubility while achieving heat resistance through the overall molecular architecture rather than extensive crosslinking.
