主要通过原位生成的辐烯与N-烷基马来酰亚胺之间的Diels-Alder反应合成了一系列三亚苯和三亚萘甲酰亚胺。由于吸电子羧酰亚胺基团的附着而获得了高电子亲和力。这些盘状分子可以在固态下组装成一维柱状结构，并通过DSC、POM和X射线衍射表征了它们的中间相性质。观察到长程有序柱状相，使其成为电子器件中潜在的 n 型半导体。
A series of triphenylene and trinaphthylene carboximides were synthesized mainly through Diels-Alder reactions between the in situ generated radialenes and N-alkylmaleimides. High electron affinity was obtained due to the attachment of electron-withdrawing carboximide groups. These disklike molecules can assemble into one-dimensional columnar structures in solid state and their mesophase properties were characterized by DSC, POM, and X-ray diffraction. Long-range ordered columnar phase was observed, qualifying them as potential n-type semiconductors in electronic devices.
