Double-spiro organic compounds and electroluminescent devices

Compound is present in the step and other of the electroluminescent volute organic compound. The volute organic compound has a configurations or structure at least three flat plate, and absorbed in which the component and an a component and reacting at room between two adjacent flat plate, and each of common of the component and two adjacent surface part in the middle. Surface part in the middle is vertical to the two adjacent flat plate. Preferably in the middle of the separating more of the surface part of the mixture of the plane of common. The spirane of greater than about 300℃ melting point and chamber within, wherein in the thermostability to the organic EL component. Similarly, wherein the volute organic compound has better sublimability, wherein providing to the physical vapour deposition utility. The suspension, the spirane a and hole injection and hole transmission and electron-injection and electronic transmission and performance, wherein the synchronous the organic EL component. Similarly compound is present of comprising at least comprising one or a layer of more of a volute organic compound with other and electrical electroluminescent device.
