Phosphorescent perylene imides.
Asymmetrically substituted perylene imide derivatives PIa and PIx display phosphorescence in glassy matrices at 77 K. The lifetime is 49.0 ms for PIa and 13.5 ms for PIx. The triplet energy is 1.79 eV for PIa and 1.68 eV for PIx as confirmed by sensitization experiments of the C(60) triplet.
متن کاملTemperature responsive phosphorescent small unilamellar vesicles.
Self-assembled lipid vesicles with embedded amphiphilic terbium(III) complexes show a strong temperature dependence of their phosphorescence intensity and lifetime in the physiological range.
متن کاملNovel host materials for blue phosphorescent OLEDs
We present two classes of host materials for blue phosphors. The first are carbazole substituted biphenyls 1-9. In these CBP-type materials the triplets are confined to one half of the molecules by using either twisted biphenyls or by a metalinkage of the carbazoles to the biphenyl. We obtained high triplet energies of 2.95-2.98 eV and high glass transition temperatures in the range of 100-120 ...
متن کاملHigh power efficiency phosphorescent poly(dendrimer) OLEDs.
We show that it is possible to produce an efficient solution-processable phosphorescent poly(dendrimer) OLED with a 32 lm/W power efficiency at 100 cd/m2 without using a charge transporting host or any improvements in light extraction. This is achieved by using the dendrimer architecture to control inter-chromophore interactions. The effects of using 4,4',4″-tris(N-carbazolyl)triphenylamine (TC...
متن کاملRed Phosphorescent Organic Light-emitting Diodes
Phosphorescent organic light-emitting diodes (OLEDs) have the great advantage of highlyefficient emission compared with conventional fluorescent OLEDs. Pt(II) porphyrins are among the most promising saturated red phosphorescent dyes, yet tuning of their properties by making structural modifications has only been attempted on a modest scale, despite the large structuraldiversity of synthetic por...
