Embodiment

[0174] Unless otherwise noted, the following syntheses were performed in dry solvents under a protective atmosphere. Also, handle metal complexes in the dark. Solvents and reagents were purchased from ALDRICH or ABCR.

[0175]A: Synthetic Ligand

[0176] 1) Imidazo[2,1-a]isoquinoline system

[0177] Synthesis of 1-aminoisoquinoline:

[0178] A mixture of 100 mmol of 1-chloroisoquinoline derivative and 600 mmol of ammonium chloride was stirred in 100 ml of thiophene at 200° C. for 20 hours. 200 ml of water was added to the cooled mixture, and the mixture was stirred at room temperature for 1 hour. The solid was filtered off with suction, washed once with 50 ml of water and subsequently suspended in a mixture of 50 ml of methanol and 150 ml of concentrated ammonia solution. The suspension was stirred at room temperature for 20 hours, the solid was filtered off, washed three times with 50 ml of 1:1 methanol / water, dried under vacuum and worked up by Kugelrohr distillation. ...

Abstract

The present invention relates to metal complexes and to electronic devices, in particular organic electroluminescent devices, comprising these metal complexes.

Description

technical field [0001] The structure of organic electroluminescent devices (OLEDs) in which organic semiconductors are used as functional materials is described, for example, in US 4539507, US 5151629, EP 0676461 and WO 98 / 27136. The luminescent materials used here are increasingly organometallic complexes showing phosphorescence rather than fluorescence (M.A. Baldo et al., Appl. Phys. Lett. 1999, 75, 4-6) For quantum mechanical reasons, Using organometallic compounds as phosphorescent emitters, it is possible to achieve up to a four-fold increase in energy and power efficiency. In general, however, there is still a need for improvements in OLEDs exhibiting triplet emission, especially in terms of efficiency, operating voltage, and lifetime. This is especially the case for OLEDs which emit in the relatively short-wave range, ie in the green, especially blue. Thus, to date, no blue-emitting triplet emitters are known which meet the technical requirements for industrial use. ...
