    • In the case of the materials according to the invention, the charge carrier mobility in the correspondingly prepared films is achieved if the molecules are composed in such a way that side chains—consisting of conjugated aromatic or heteroaromatic systems—are attached in direct conjugation to a central aromatic or heteroaromatic ring so that the total molecule acquires an octupolar structure. This octupolar structure permits an effective π-π interaction of the molecules with one another in a manner such that stacking of a plurality of molecules along an imaginary axis (central ring) can take place and various stacks from among these stacks can interact with one another by intermeshing of the side chains. The electronic properties of the materials are determined both by the arrangement of the molecules in a layer and by the molecular design. The type of side chains and of the central ring which is electronically coupled to the side chains and ideally reinforces the effects in comparison with side chains considered in isolation is important for this purpose.
    • 在根据本发明的材料的情况下,如果分子以使得由共轭芳族或杂芳族体系组成的侧链与直接共轭连接的方式组成的方式实现相应制备的膜中的载流子迁移率 中心芳族或杂芳族环,使得总分子获得八极结构。 这种八极结构允许分子彼此有效的pi-pi相互作用,使得沿着假想轴(中心环)堆叠多个分子可以发生,并且这些堆中的各种叠层可以彼此相互作用 通过侧链的相互啮合。 材料的电子性质通过层中分子的排列和分子设计来确定。 电子耦合到侧链的侧链和中心环的类型和理想地加强与隔离考虑的侧链相比的效果对于此目的是重要的。
