Disclosed herein are a phenanthrene-based compound with a high-refractive index and a preparation method therefor. The compound has a phenanthrene-based complex cardo structure and can be used as a monomer in optical resins requiring a refractive index of 1.7 or higher. Due to the phenanthrene-based complex cardo structure of the compound, the fluidity of the molecular chains can be maximally suppressed, allowing for the production of resins with excellent thermal stability, characterized by a high glass transition temperature.

Provided herein are methods for producing cyclic and acyclic ketones from trimerization and dimerization of alkyl ketones, including for example methyl ketones. Such cyclic and acyclic ketones may be suitable for use as fuel and lubricant precursors, and may be hydrodeoxygenated to form their corresponding cycloalkanes and alkanes. Such cycloalkanes and alkanes may be suitable for use as fuels, including jet fuels, and lubricants.
