Abstract
An electroluminescent element in which at least one layer containing at least one of novel hydrocarbon compounds with an anthracene ring and a fluorene ring directly bound is held between a pair of electrodes. The compounds can advantageously be used in a luminescent element and provide an organic electroluminescent element having an excellent luminescent efficiency and a long luminescent life.
