Abstract

The present invention relates inter alia to functional materials for the treatment and/or prophylaxis and/or diagnosis of diseases and/or cosmetic conditions. The functional materials can be used for the preparation of light emitting devices comprising fibers as light emitting elements.

Claims

1-18. -18. (canceled)

19. A method of preparing a device for the treatment and/or prophylaxis and/or diagnosis of diseases and/or cosmetic conditions which comprises utilizing a functional material selected from host materials, emissive materials (EM), hole injection materials (HIM), hole transport materials (HTM), hole blocking materials (HBM), electron injection materials (EIM), electron transport materials (ETM), electron blocking materials (EBM), exciton blocking materials (ExBM), metal complexes, and phosphor materials wherein the device comprises at least one organic light emitting fiber.

20. The method as claimed in claim 19, wherein the fiber comprises a fiber core having an outer first electrode;

at least one organic light emitting layer positioned over an outer surface of the first electrode; and

a light transmissive second electrode positioned over the organic light emitting layer;

wherein the at least one organic light emitting layer comprises at least one organic material that emits light when a voltage is applied across the first and second electrode.

21. The method as claimed in claim 19, wherein the device is flexible, or the fiber is flexible, or both the device and the fiber are flexible.

22. The method as claimed in claim 19, wherein the device is an ambulatory device and comprises an attachment means for attaching the device to a human or animal subject.

23. The method as claimed in claim 19, wherein the device is a plaster, bandage, blanket, sleeping bag, sleeve, implantable probe, nasogastric tube, chest drain, pad, stent, patch, canvas or any kind of clothes, or devices covering at least one tooth in the mouth.

24. The method as claimed in claim 19, wherein the organic light emitting fiber is an organic light emitting diode (OLED).

25. The method as claimed in claim 19, wherein the device is used in a method for the treatment and/or prophylaxis and/or diagnosis of skin diseases and/or cosmetic skin conditions.

26. The method as claimed in claim 19, wherein the device is used in a method for the treatment and/or prophylaxis and/or diagnosis of skin diseases and/or cosmetic skin conditions selected from acne, psoriasis, eczema, dermatitis, atopic dermatitis, edema, vitiligo, Bowens disease, tumors, pre-malignant tumors, malignant tumors, basal cell carcinomas, squamous cell carcinomas, secondary metastases, cutaneous T-cell lymphomas, solar keratosis, arsenical keratosis, radiodermatitis, and cellulite.

27. The method as claimed in claim 19, wherein the device is used in a method for the treatment and/or prophylaxis and/or diagnosis of infections and inflammatory, neurological, and psychological diseases and/or conditions.

28. The method as claimed in claim 19, wherein the device is used in a method for the disinfection of soft drinks, beverages, water, drinking water, foodstuff, and nutrition.

29. The method as claimed in claim 19, wherein the device is used in a method for the application in photodynamic therapy (PDT).

30. The method as claimed in claim 19, wherein the device is used in a method for the treatment and/or prophylaxis of jaundice and crigler naijar.

31. A process for the preparation of a device for the treatment and/or prophylaxis and/or diagnosis of diseases and/or cosmetic conditions, wherein the device comprises at least one organic light emitting fiber, which comprises utilizing a composition comprising at least one functional material selected from host materials, emissive materials (EM), hole injection materials (HIM), hole transport materials (HTM), hole blocking materials (HBM), electron injection materials (EIM), electron transport materials (ETM), electron blocking materials (EBM), exciton blocking materials (ExBM), metal complexes, and phosphor materials and at least one further compound.

32. A device for the treatment and/or prophylaxis and/or diagnosis of diseases and/or cosmetic conditions, wherein the device comprises at least one organic light emitting fiber.

33. The device according to claim 32, wherein the light emitting fiber comprises a functional material selected from host materials, emissive materials (EM), hole injection materials (HIM), hole transport materials (HTM), hole blocking materials (HBM), electron injection materials (EIM), electron transport materials (ETM), electron blocking materials (EBM), exciton blocking materials (ExBM), metal complexes, and phosphor materials.

34. The device according to claim 32 for the treatment and/or prophylaxis and/or diagnosis of skin diseases and/or cosmetic skin conditions selected from acne, psoriasis, eczema, dermatitis, atopic dermatitis, edema, vitiligo, Bowens disease, tumors, pre-malignant tumors, malignant tumors, basal cell carcinomas, squamous cell carcinomas, secondary metastases, cutaneous T-cell lymphomas, solar keratosis, arsenical keratosis, radiodermatitis, cellulite, skin desensibilisation, infections, inflammation, neurological and psychological diseases and/or conditions, photodynamic therapy (PDT), jaundice and crigler naijar.

35. A method for the treatment and/or prophylaxis and/or diagnosis of diseases and/or conditions which comprises utilizing an organic light emitting fiber.

36. The method as claimed in claim 35, wherein the conditions are diagnosis of cosmetic conditions.
