Abstract
The present invention relates to a material for an organic electro-optical device and an organic electro-optical device including the same. More particularly, the present invention relates to a material having thermal stability of a glass transition temperature of 120° C. or more and a thermal decomposition temperature of 450° C. or more, and being capable of providing an organic electro-optical device having high efficiency and a long life-span due to less crystallization and improved amorphous properties in a material for an organic electro-optical device. The material for an organic electro-optical device can be used singularly or as a host material in combination with a dopant, and includes an asymmetric fluorene derivative compound. An organic electro-optical device including the material for an organic electro-optical device is also provided.
