Title: MATERIAL FOR ORGANIC ELECTROLUMINESCENT DEVICE, ORGANIC ELECTROLUMINESCENT DEVICE, ILLUMINATING DEVICE AND DISPLAY
Abstract:
A material for organic electroluminescent devices and a novel compound are disclosed which enable to obtain an organic electroluminescent device, an illuminating device and a display having high luminous efficiency and long life. This material for organic electroluminescent devices is characterized by being a compound which has a molecular weight of not less than 450 and is represented by the following general formula (1): (wherein R1 represents an alkyl group which may have a substituent, a cycloalkyl group which may have a substituent, an aryl group which may have a substituent or a heterocyclic group which may have a substituent; Z1 and Z2 independently represent an atomic group necessary for forming a five-membered, six-membered or seven-membered nitrogen-containing aromatic heterocyclic ring structure; and Y1 represents a divalent linking group or just a bonding hand).
