ABSTRACT:
The present invention discloses a phenanthrene derivative having the following structure:wherein Ar1and Ar2independently are phenyl, nathphyl, heterocyclic group, polycyclic aromatic or polycyclic heterocyclic group with at least one conjugated substituent. The conjugated substituent can be an electron withdrawing group or electron donating group. The phenanthrene derivatives have semiconductor properties of electron transfer, electroluminescence (EL), and photoluminescence (PL). Intermolecular stacking can be avoided and electron-luminescent emission stability is enhanced when the derivatives are applied as a light-emitting material in organic EL devices due to the presence of the two stereo cyclopentane rings, such as a host compound or a dopant emitting blue light.
