Claims25
An electroluminescent device comprised of an anode, a cathode, and a metal thioxinoid of the formula ##STR8## wherein M represents a metal;
- each n is a number of from 1 to 3;
- N is nitrogen, S is sulfur, and Z is benzo{f}-quinoline, substituted benzo{f}-quinoline, benzo{h}quinoline, substituted benzo{h}quinoline, quinoxaline, 2-phenylbenzoxazole, or 2-phenylbenzothiazole.
An electroluminescent device comprising a luminescent layer comprised of a hole injecting and transporting component, and an electron injecting and transporting metal thioxinoid compound of the following Formula, ##STR11## wherein M represents a metal;
- each n is a number of from 1 to 3;
- N is nitrogen, S is sulfur, and Z is benzo{f}-quinoline, substituted benzo {f}-quinoline, benzo {h}quinoline, substituted benzo{h}quinoline, quinoxaline, 2-phenylbenzoxazole, or 2-phenylbenzothiazole, and a fluorescent dye, and which luminescent layer is sandwiched between a cathode and an anode.
A metal thioxinoid of the formula:
- ##STR14## wherein M represents a metal;
- each n is a number of from 1 to 3;
- N is nitrogen, S is sulfur, and Z is benzo {f}-quinoline, substituted benzo{f}-quinoline, benzo{h}quinoline, substituted benzo{h}quinoline, quinoxaline, 2-phenylbenzoxazole, or 2-phenylbenzothiazole.
