Merck, 900438-1G, Super yellow light-emitting PPV copolymer

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 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).
