Abstract: The invention relates to a cover 1 for an aperture in a wall, in particular a vehicle wall, for a rod-like force-transmitting means, in particular a handbrake lever. The cover has an opening region 2 with a through-opening 3 through which the force-transmitting means can pass and a support region 4 for supporting the cover on the wall. For adaptation to a change of position of the actuated force-transmitting means at least in a plane of movement at least approximately perpendicular to an opening axis a of the through-opening 3, the opening region 2 of the cover 1 can be coupled to the force-transmitting means in a movement-effecting manner such that its position can be changed with respect to the aperture. For planar covering of the aperture there is provided a flexible wall element 10 which is connected to the opening region 2 and to the support region 4 or is connectable to the opening region 2 and to the aperture, and which covers at least a gap between support region 4 and through-opening 3.

Abstract: The invention relates to regioregular polyselenophenes, to their use as semiconductors or charge transport materials, in optical, electro-optical or electronic devices, and to optical, electro-optical or electronic devices comprising them.

Abstract: The invention relates to a process for coupling thiophene or selenophene compounds, in particular for preparing conjugated thiophene or selenophene polymers with high molecular weight and high regioregularity, and to novel polymers prepared by this process. The invention further relates to the use of the novel polymers as semiconductors or charge transport materials in optical, electrooptical or electronic devices including field effect transistors (FETs), thin film transistors (TFT), electroluminescent, photovoltaic and sensor devices. The invention further relates to FETs and other semiconducting components or materials comprising the novel polymers.
