Description

General description

Super yellow light emitting PPV copolymer can form a thin film of poly(1,4-phenylenevinylene) (PPV) with high efficiencies. It has conjugated polymers as the backbone that can be soluble in water upon the incorporation of lipophilic solubilizing linkers.

Application

Features:

• soluble super yellow light-emitting PPV copolymer
• excellent reproducibility
• broad emission spectrum
• very high efficiency
• very low operation voltage/for PM 100000 cd/m² pulsed <10 V
• very long DC & AC lifetime

Typical performance measured in standard device stack (ITO/PEDOT: PSS 20 nm/PDY-132 80 nm/Ba 6 nm/Ag 150 nm):

• max. efficiency: 11 Cd/A
• V_on: 2.2 V
• V @ 100 cd/m²: 3.0 V
• V @ 1000 cd/m²: 4.3 V
• max. power eff.: 10 lm/W
• external quantum eff.: 5.3%
• CIE1931 @ 100 cd/m²: (0.50, 0.49)
• DC lifetime @ 100 cd/m² @ RT: >>220000
• AC lifetime @ 200 cd/m² @ RT: 11000

PDY-132 can be used in the preparation of electroluminescent line material, which can be used for making line art by direct-write patterning. It can also be used as a fluorescent material with the absorption peak at 450 nm, that can be developed by blade coating on the substrates of the transfer printed micro-sized light emitting diodes (μLED).
