Two reactive phenanthrene derivatives, 4-(1H phenanthrol [9,10-d] imidazole-2-yl) benzaldehyde (PIB) and 6,9-dimethoxyphenanthro[9,10-c]furan-1,3-dione (PA) with high fluorescent quantum yields were prepared and used as fluorescent marker in fluorescence microscopy. In particular, silane modified μmZeolite-L containing amino group (-NH2) in the surface were labeled with the phenanthrene derivatives
两种反应性菲衍生物,4-(1H 菲醇 [9,10-d] 咪唑-2-基) 苯甲醛 (PIB) 和 6,9-二甲氧基菲[9,10-c]呋喃-1,3-二酮 (PA)制备了具有高荧光量子产率的荧光标记物,并将其用作荧光显微镜中的荧光标记物。特别是硅烷改性的μmZeolite-L含氨基(-NH 2) 表面被菲衍生物标记,允许良好的成像分辨率和光谱测量。由于其分子内电荷转移特性,探针的大斯托克斯位移的存在使化合物在共聚焦激光荧光显微镜中具有优势,因为在激发和发射波长中信号易于分离。另一方面,这些结果开辟了使用这些探针可视化通常用作热和光化学反应催化剂的沸石基材料的可能性。
