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 کاملPhosphorescent light-emitting iridium complexes serve as a hypoxia-sensing probe for tumor imaging in living animals.
Iridium complex is a promising organic light-emitting diode material for next generation video displays that emits phosphorescence quenched by oxygen. We used this oxygen-quenching feature for imaging tumor hypoxia. Red light-emitting Ir(btp)(2)(acac) (BTP) presented hypoxia-dependent light emission in culture cell lines, whose intensity was in parallel with hypoxia-inducible factor-1alpha imag...
متن کاملRemarkable cardinals
To a large extent, the scientific work of both Peter Koepke and Philip Welch has always been inspired by Ronald Jensen’s fine structure theory and his Covering Lemma for L, the constructible universe. Cf., e.g., their joint papers [5] and [6]. In this paper we aim to play with the theme that large cardinals compatible with “V=L,” specifically: remarkable cardinals, allow us to create situations...
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 ...
