摘要：

Novel blue emitters with two bulky substituents on the 2,6-position of 9,10-diphenylanthracene (DPAN), which can provide effective hindrance to the intermolecular packing, were synthesized, characterized, and used in the fabrication of organic light emitting diodes (OLEDs). DSC thermograms and theoretical calculations of 3-dimensional structures of Ph-DPAN, Flu-DPAN and TPA-DPAN, support that they have an amorphous and non-coplanar structure. With application of these newly non-doped, blue emitting materials in a multilayer device structure, it is possible to achieve a current efficiency of 4.6-5.8 cd/A for DPAN derivatives.
