Abstract
A blue electroluminescent material based on a binaphtyl compound of the general formula (I). Particular embodiments having the general formula have good solubilities in common organic solvents, resist crystallization and can be sublimed in a device fabrication process. These properties enable the fabrication of organic electroluminescent devices.
