COMPOUND WITH AN INDOLE GROUP COMBINED IN BOTH ENDS OF TETRAHYDRO PYRENE OR TETRAHYDRO PHENANTHRENE AND AN ORGANIC ELECTROLUMINESCENT DEVICE WITH IMPROVED LUMINOUS EFFICIENCY AND POWER EFFICIENCY INCLUDING THE SAME
COMPOUND WITH AN INDOLE GROUP COMBINED IN BOTH ENDS OF TETRAHYDRO PYRENE OR TETRAHYDRO PHENANTHRENE AND AN ORGANIC ELECTROLUMINESCENT DEVICE WITH IMPROVED LUMINOUS EFFICIENCY AND POWER EFFICIENCY INCLUDING THE SAME
PURPOSE: A compound is provided to improve luminous efficiency, power efficiency, lifetime and stability.;CONSTITUTION: A compound is indicated as the following chemical formula 1. The A is selected from a group consisting of functional groups of the 1 -a, the 1-b, and the 1-c of the chemical formula 1. The Ra and the Rb or the Rb and the Rc make a fuse loop. When the Ra and the Rb make the fuse loop, the Rc is hydrogen. When the Rb and the Rc make the fuse loop, the Ra is hydrogen. The Ar1- the Ar4 are respectively selected from a C1-40 alkyl group, a C3-40 cycloalkyl group, a C3-40 heterocycloalkyl group, a C6-60 aryl group, a C5-60 heteroaryl group, a C1-40 alkyloxy group, a C6-60 aryloxy group and a C6-60 arylamine group.;COPYRIGHT KIPO 2013
