2,4,5- thoria reel substitution imidazole chemical compound and 1,2,4,5- tetra- aryl substitution imidazole chemical compound

摘要

Is displayed with formula (1) as for the imidazole chemical compound which, blue luminous efficiency is high, at the same time because, it is stability, it is ideal as a luminescent material for the organic electro- luminescence element and the organic solar array.(In formula, R¹ displays phenyl group and the like, R² displays the hydrogen atom and the like, R³, R⁴, R¹⁰ and R¹¹, in the respective independence, displays the hydrogen atom and the halogen atom etc, R⁵, R⁶, R⁷, R⁸ and R⁹, in the respective independence, displays the hydrogen atom and phenyl group etc. However, inside R⁵ - R⁹ one displays the substituent other than the hydrogen atom at least.)
