First claim
Opening claim text (preview).
What is claimed is: 1. A composition comprising a fluorinated polymer, an organic semiconductor material and a dopant, wherein the fluorinated polymer has a saturated vapor pressure at 300° C. of at least 0.001 Pa. 2. The composition according to claim 1 , wherein the fluorinated polymer has a refractive index in a wavelength range of from 450 nm to 800 nm of at most 1.5. 3. The composition according to claim 1 , wherein the fluorinated polymer is a fluorinated polymer having an alicyclic ring in its main chain. 4. The composition according to claim 1 , wherein the fluorinated polymer has a mass average molecular weight of from 1,500 to 50,000. 5. The composition according to claim 1 , wherein the proportion of the fluorinated polymer is from 30 to 70 vol % to the total amount of the fluorinated polymer, the organic semiconductor material and the dopant. 6. The composition according to claim 1 , wherein the proportion of the dopant is from 10 to 200 parts by mole per 100 parts by mole of the total amount of substance of the organic semiconductor material. 7. The composition according to claim 1 , which has a surface roughness of at most 1.0 nm by RMS. 8. The composition according to claim 1 , which has an absorption coefficient in a wavelength range of from 450 nm to 800 nm of at most 5,000 cm −1 . 9. The composition according to claim 1 , which has a refractive index in a wavelength range of from 450 nm to 800 nm of at most 1.60. 10. An organic photoelectronic element having a layer comprising the composition as defined in claim 1 . 11. The organic photoelectronic element according to claim 10 , wherein the organic photoelectronic element is an organic EL device. 12. A method for producing a layer comprising the composition as defined in claim 1 , which comprises co-depositing the fluorinated polymer, the organic semiconductor material and the dopant on a substrate. 13. A method for producing the organic photoelectronic element as defined in claim 10 , which comprises co-depositing the fluorinated polymer, the organic semiconductor material and the dopant on a substrate.
