Carbon encapsulated copper oxide nanoparticles (CuONPs@C) fabricated using copper metal organic frameworks (Cu-MOFs) used as reusable nanocatalysts in Ullmann C[sbnd]N coupling reactions for synthesizing optoelectronic triphenylamine (TPA) and carbazole (CBZ) derivatives. The formation of CuONPs in carbon matrix was confirmed by powder X-ray diffraction (PXRD), X-ray photoelectron spectroscopy (XPS) and high-resolution transmission electron microscopy (HR-TEM). The catalytic activity of CuONPs@C was performed with diphenylamine/carbazole with substituted aryl halides in presence of mild K2CO3 base that produced triarylamines with 63–83% yields. Carbazole triarylamines exhibited strong solid state fluorescence (Φf = 14.54–36.32%) with λmax between 370 and 420 nm.
