The present invention relates to the use of a compound represented by the general formula (I)
wherein A1 and A2 are independently selected from C1 to C60 carbon-containing groups; A3 to A9 are independently selected from hydrogen, C1 to C60 carbon-containing groups, or halogen; R1 and R2 are independently selected from C1 to C60 carbon-containing groups which are attached to the phosphorous atom by a sp3-hybridized carbon atom; X is a single covalent bond or a spacer group consisting of 1 to 120 covalently bound atoms; in a semiconducting layer comprised in an electronic device, a respective semiconducting layer, a respective electronic device and respective compounds.
本发明涉及通式 (I) 所代表的化合物的用途
其中,A1 和 A2 独立地选自 C1 至 C60 含碳基团;A3 至 A9 独立地选自氢、C1 至 C60 含碳基团或卤素;R1 和 R2 独立地选自 C1 至 C60 含碳基团,这些基团通过 sp3 杂化碳原子连接到
磷原子上;X 是单个共价键或由 1 至 120 个共价结合原子组成的间隔基团;在电子设备、各自的半导体层、各自的电子设备和各自的化合物中所包含的半导体层中使用。
