The invention concerns Spirobifluorene derivatives having the general formula (II) and the corresponding, radical anions that can be represented via the general formula (II):
in which K, L, M and N, the same or different from each other, are independently: H or A-C═O, with the proviso that it is never K=L=M=N═H, wherein A is an aromatic group, possibly substituted with at least an R′ group selected in the group of the substituents commonly used in organic chemistry and/or at least one R group where R=aliphatic radical. The invention also concerns the method for preparing said derivatives and radical anions. Said compounds are applied in the field of components for molecular electronics, in particular systems for electroluminescence, molecular-based computational systems, OLEDs, molecular switching components, components for non-linear optics, field-effect transistors and semiconductors with negative differential resistance.
本发明涉及具有通式(II)的螺二芴衍生物和相应的、可通过通式(II)表示的基阴离子:
其中 K、L、M 和 N(相同或不同)各自为H或A-C═O,但绝不是K=L=M=N═H,其中A是芳香基团,可能被至少一个R′基团取代,该R′基团选自有机化学中常用的取代基和/或至少一个R基团,其中R=脂肪基。本发明还涉及制备上述衍生物和基阴离子的方法。所述化合物可应用于分子电子学元件领域,特别是电致发光系统、分子计算系统、有机发光二极管、分子开关元件、非线性光学元件、场效应晶体管和负微分电阻半导体。
