A new approach for the synthesis of acetylene‐substituted naphthalene diimides is developed. The obtained compounds emit green light with quantum photoluminescence yields of ca. 6 % in chloroform and in the range 3–12 % as thin films. Under an applied external voltage, they exhibit orange or red electroluminescence.

简单方法制备的萘二酰亚胺及其在有机电子学中的表征

开发了一种合成乙炔取代的萘二酰亚胺的新方法。所获得的化合物发射绿光，其量子光致发光产率约为。在氯仿中为6％，薄膜形式则为3–12％。在施加的外部电压下，它们呈现橙色或红色电致发光。
