A directarylation of a variety of electron-deficientheterocycles with arylboronic acids has been developed. This new reaction proceeds readily at room temperature using inexpensive reagents: catalytic silver(I) nitrate in the presence of persulfate co-oxidant. The scope with respect to heterocycle and boronic acid coupling partner is broad, and sensitive functional groups are tolerated. This method

The present invention relates to an organic electroluminescent device comprising at least one light-emitting layer between an anode and a cathode, wherein the light-emitting layer comprises a host and a phosphorescent dopant; the host consists of multi-component host compounds; at least a first host compound of the multi-component host compounds is a bicarbazole derivative containing pyridine, and a second host compound is a carbazole derivative including a nitrogen-containing heteroaryl group. According to the present invention, an organic electroluminescent device using the multi-component host compounds has high efficiency and long lifespan compared to a conventional device using one component of a host.
