20 Claims

1. A luminescence device, comprising:

a first electrode;

a second electrode on the first electrode; and

at least one functional layer between the first electrode and the second electrode,

wherein the at least one functional layer comprises a polycyclic compound represented by Formula 1:

wherein in Formula 1,

X is O, S, Se, CR₄R₅, SiR₆R₇, or

R₁to R₇are each independently a hydrogen atom, a deuterium atom, a substituted or unsubstituted silyl group of 1 to 30 carbon atoms, a substituted or unsubstituted aryl amine group of 6 to 30 carbon atoms for forming a ring, a substituted or unsubstituted alkyl group of 1 to 30 carbon atoms, a substituted or unsubstituted alkenyl group of 2 to 30 carbon atoms, a substituted or unsubstituted aryl group of 6 to 60 carbon atoms for forming a ring, or a substituted or unsubstituted heteroaryl group of 2 to 60 carbon atoms for forming a ring, or are combined with an adjacent group to form a ring,

“a” to “c” are each independently an integer of 0 to 4, and

wherein, when X is O, S, CR₄R₅, or SiR₆R₇,

at least one selected from among a to c is 1 to 4, and a corresponding at least one selected from among R₁to R₃are each independently represented by any one from RO-1 to RO-14 and RO-16 to RO-20:

when X is Se,

at least one selected from R₁to R₃is a substituted or unsubstituted aryl group of 6 to 60 carbon atoms for forming a ring, or a substituted or unsubstituted heteroaryl group of 2 to 60 carbon atoms for forming a ring, and

a sum of “a” to “c” is 1 or more, and

when X is

-(L₁)_p-(Ar₁)_qis represented by any one from RN-1 to RN-11, RN-16 to RN-18 and RN-20 to RN-48:
