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.

Two new carbazole-containing aromatic imides were synthesized by three-step synthetic pathway with the moderate yields up to 76%. The compounds were investigated theoretically. TD-DFT computational studies revealed low singlet-triplet energy differences. The compounds were found to have relatively high thermal stability with 5% mass loss temperatures in the range of 280–310 °C. Phthalimide-based compound exhibited aggregation-induced emission enhancement and thermally activated delayed fluorescence with photoluminescence quantum efficiency of 20% in the solid state. Structure-properties relationship of this compound was investigated and it was found that charge-transfer through space mechanism is responsible for the emission. Series of green-emitting doped and non-doped electroluminescent devices were fabricated based on the carbazole-phthalimide derivative were fabricated to reveal best-performing mCP-doped device demonstrating maximum external quantum efficiency of 2.4% with current efficiency of 6.6 cd/A and power efficiency of 4.0 lm/W with maximum brightness of 8300 cd/m2.
