Claim 1:
2. The light emitting device of claim 1, wherein the chiral complex emitter has a structure represented by General Formula IA:, , wherein:
M represents Pt2+, Pd2+, Ir+, Rh+, or Au3+;
each R1 and R2 in (R1)2 and (R2)2 independently represents hydrogen, halogen, hydroxyl, nitro, thiol, or substituted or unsubstituted: C1-C4 alkyl or amino;
Y1a represents O; S; NR3a, wherein R3a represents substituted or unsubstituted C1-C4 alkyl; Si(R3b)2, wherein each R3b in (R3b)2 independently represents substituted or unsubstituted C1-C4 alkyl; or C(R3c)2, wherein each R3c in (R3c)2 independently represents hydrogen or substituted or unsubstituted C1-C4 alkyl;
Y1b is present or absent, and if present, represents a covalent bond or O; S; NR4a, wherein R4a represents substituted or unsubstituted C1-C4 alkyl; Si(R4b)2, wherein each R4b in (R4b)2 independently represents substituted or unsubstituted C1-C4 alkyl; or C(R4c)2, wherein each R4c in (R4c)2 independently represents hydrogen or substituted or unsubstituted C1-C4 alkyl;
each of Y2a, Y2b, Y2c, and Y2d, valency permitting, independently represents C or N or NR5a, or CR5b, wherein each of R5a and R5b independently represents hydrogen, halogen, hydroxyl, nitro, thiol, or substituted or unsubstituted: C1-C4 alkyl or amino;
each of Y3a, Y3b, Y3c, Y3d, Y3e, Y4a, Y4b, Y4c, Y4d, and Y4e, valency permitting, independently represents C; N; O; S; NR6a or CR6b, as permitted by valency, wherein each of R6a and R6b independently represents hydrogen or substituted or unsubstituted C1-C4 alkyl; or Z(R6c)2, wherein Z is C or Si, and each R6c in (R6c)2 independently represents hydrogen or substituted or unsubstituted C1-C4 alkyl;
m is 1 or 2;
n is 1 or 2;
the open dotted circle  indicates partial or full unsaturation of the ring with which it is associated; and
at least one of M, R1, R2, Y1a, Y1b, Y2a, Y2b, Y2c, Y2d, Y3a, Y3b, Y3c, Y3d, Y3e, Y4a, Y4b, Y4c, Y4d, Y4e is a chiral center.
