AI Technical Summary

Technical Problem

Existing optical materials lack high refractive index, low thermal expansion, and mechanical strength, and there is a need for naphthalene compounds with polymerizable functional groups to enhance light extraction efficiency.

Method used

A naphthalene compound is synthesized by reacting a naphthalenedithiol compound with a styrene, alkyne, or alkene compound, featuring two polymerizable functional groups, and can be further haloalkylated to introduce halogen atoms, providing a novel compound for optical applications.

Benefits of technology

The naphthalene compound exhibits a high refractive index, improved compatibility with solvents and resin components, and yields cured products with superior thermal stability and mechanical strength.
