Organic light-emitting diode luminaires

A process for making an OLED luminaire, comprising:

• providing a substrate having a first patterned electrode thereon;
• depositing a first liquid composition in a first pixellated pattern to form a first deposited composition, the first liquid composition comprising a first electroluminescent material in a first liquid medium, said first electroluminescent material having a first emission color;
• depositing a second liquid composition in a second pixellated pattern which is laterally spaced from the first pixellated pattern to form a second deposited composition, the second liquid composition comprising a second electroluminescent material in a second liquid medium, said second electroluminescent material having a second emission color;
• depositing a third liquid composition in a third pixellated pattern which is laterally spaced from the first and second pixellated patterns to form a third deposited composition, the third liquid composition comprising a third electroluminescent material in a third liquid medium, said third electroluminescent material having a third emission color;
• drying the deposited compositions to form pluralities of pixels;
• and
• forming a second electrode over all the pixels;
• wherein one of the emission colors is blue, one of the emission colors is green, and one of the emission colors is red-orange;
• wherein the 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, g, 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.
