Organic light-emitting diode luminaires

An organic light-emitting diode luminaire comprising a patterned first electrode, a second electrode, and a light-emitting layer therebetween, the light-emitting layer comprising:

• a first plurality of pixels comprising a first electroluminescent material having an emission color that is blue;
• a second plurality of pixels comprising a second electroluminescent material having an emission color that is green, the second plurality of pixels being laterally spaced from the first plurality of pixels;
• and
• a third plurality of pixels comprising a third electroluminescent material having an emission color that is red-orange, the third plurality of pixels being laterally spaced from the first and second pluralities of pixels;
• wherein the additive mixing of the three emitted colors results in an overall emission of white light;
• and
• wherein the first electroluminescent material with blue emission color has Formula I
• wherein:
• R14, R15, R16 and R17 are the same or different and are selected from the group consisting of H, D, and alkyl, where R14 and R15 groups or R16 and R17 groups may be joined together to form a 5- or 6-membered aliphatic ring;
• R18 and R19 are the same or different and are selected from the group consisting of D, alkyl groups, silyl groups, m-phenyl, o-phenyl, p-phenyl, m-N-carbazolyl, and p-N-carbazolyl;
• R20 is the same or different at each occurrence and is selected from the group consisting of D, alkyl groups, silyl groups, phenyl, and biphenyl, or two adjacent R20 groups can join together to form a naphthyl or fluorenyl group;
• a and b are the same or different and are an integer from 0-10;
• c and d are the same or different and are an integer from 1-5;
• f, q, h, and i, are the same or different at each occurrence and are an integer from 0-4;
• and
• e and j are the same or different at each occurrence and are an integer from 0-5.
