Two star‐shaped molecules with benzene core and three naphthalene diimide (NDI) side arms were facilely prepared by two‐step imidization reaction from the 1,4,5,8‐naphthalenetetracarboxylic dianhydride. Two compounds showed the similar UV–vis absorption band as well as NDI. It was found that they displayed bathochromic shift of their UV–vis absorption and emission spectra in film compared with that
通过1,4,5,8-萘四甲酸二酐的两步酰亚胺化反应,可轻松制备两个带有苯核的星形分子和三个萘二酰亚胺(NDI)侧臂。两种化合物显示出相似的UV-vis吸收带和NDI。研究发现,与溶液相比,它们在薄膜中的紫外可见吸收和发射光谱发生红移,这归因于固态分子之间的聚集。通过循环伏安法和低洼LUMO能级观察到可逆还原过程(-3.83电子伏特为1A,-3.87电子伏特为1B)推导出,这表明,这两种化合物具有良好的电子受主性和可作为潜在ñ -打字材料。
