Abstract: Organic electroluminescent device comprising an anode, a cathode, at least one emission layer and an organic semiconducting layer; wherein the organic semiconducting layer is arranged between the at least one emission layer and the cathode; wherein the organic semiconducting layer comprises; a) a first organic compound comprising a first C10 to C42 arene structural moiety and/or a first C2 to C42 heteroarene structural moiety, wherein i) the dipole moment of the first organic compound, computed by the TURBOMOLE V6.5 program package using hybrid functional B3LYP and Gaussian 6-31G* basis set, is from 0 to 2.5 Debye; and ii) the LUMO energy level of the first organic compound in the absolute scale taking vacuum energy level as zero, computed by the TURBOMOLE V6.5 program package using hybrid functional B3LYP and Gaussian 6-31G* basis set, is in the range from ?1.7 eV to ?2.

Abstract: A device serves for optically scanning a moving material web. The device is formed by a CCD camera comprising a lens and a CCD receiving element, which is provided with photodiodes. So as to be able to exactly adjust the area of the material web scanned by means of the device, the CCD receiving element can be adjusted transversely in relation to the optical axis of the lens. For adjusting the CCD receiving element, a template with a structure is provided. This structure is detected by the photodiodes, and the signals emitted by the photodiodes act on a controlling device. The controlling device adjusts the CCD receiving element so that it is aligned with the structure of the template.
