HYDROCARBONS, CHARGE TRANSFER MATERIALS, CHARGE TRANSFER MATERIAL COMPOSITIONS, AND ORGANIC ELECTROLUMINESCENT DEVICES

摘要

Novel hydrocarbons which are excellent in heat resistance and light resistance and in solubility in organic solvents and which exhibit high energy levels of excited singlet and triplet states and wide electric oxidation-reduction potentials have partial structures represented by the general formula (I) in the molecule: (I) wherein G is a substituent represented by the general formula (II); and R¹ and R² are each independently an arbitrary hydrocarbon group, with the proviso that the benzene ring to which R¹, R² and G are bonded has no substituent except R¹, R² and G: (II) wherein R³ to R⁵ are each independently hydrogen or an arbitrary hydrocarbon group, with the proviso that the terphenyl group in the general formula (II) has no substituent except R³ to R⁵.
