Xanthene derivative compound having high refractive index and (co)polymer comprising same

Abstract

The present disclosure relates to a xanthene derivative compound with a high refractive index and a manufacturing method therefor. More specifically, provided herein is a compound that has a xanthene-based complex cardo structure and a high refractive index and can be used as a monomer in optical resins requiring a refractive index of 1.7 or higher, and a (co)polymer and an optical lens manufactured therefrom. Given, the xanthene-based complex cardo structure of the compound maximally suppresses the fluidity of the molecular chains and can find applications in the production of resins with high glass transition temperature and excellent thermal stability.
