We designed new three limb structured anthracene derivatives, PNA, NNA and FNA, which are composed of an anthracene core and naphthalene units at the 9,10-positions of anthracene and phenyl, naphthalene and fluorene units at the 2,3-positons of anthracene. The effect of the introduced limbs on the 2,3,9,10-positions of anthracene was studied. The doped EL devices using ADN as a host and (3% PNA or NNA or FNA) as a dopant showed similar maximum quantum efficiency of 3.9%–4.3% with high color purity of (0.15, 0.13).
► New three limb structured anthracene derivatives were synthesized. ► The structures were 3-dimensionally highly twisted non-coplanar. ► New three limb structured anthracenes as dopant exhibited efficiency of 3.9–4.3%. ► The doped EL devices showed high color purity of (0.15, 0.13).
