摘要:
该发明涉及具有一般式(II)的螺联二芴衍生物以及可以通过一般式(II)表示的相应的自由基阴离子,其中K、L、M和N,彼此相同或不同,独立地是:H或A-C=O,但须注意永远不会是K = L = M = N = H,其中A是一个芳香族基团,可能被至少一个R'基团取代,所述R'基团选自有机化学中常用的取代基团群,和/或至少一个R基团,其中R = 脂肪基团。该发明还涉及制备上述衍生物和自由基阴离子的方法。这些化合物应用于分子电子组件领域,特别是应用于电致发光系统、基于分子的计算系统、有机发光二极管(OLED)、分子开关组件、非线性光学组件、场效应晶体管和具有负微分电阻的半导体。

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.
