Facile Synthesis of π Conjugated Heptazine PPy/gC3N4 Nanocomposite as an Emissive Layer Material for OLED Applications

Heptazine-based \(\uppi \) conjugated gC3N4 has represented itself as a novel metal-free compound due to its unusual electrical, thermal, and optical behavior. gC3N4 and Puppy/gC3N4 (5, 10, and 15 wt.%) nanocomposites were synthesized via thermal polycondensation and in situ polymerization methods, respectively1. PPy/gC3N4 nanocomposite was scrutinized and optimized using X-ray diffraction (XRD), field emission electron microscopy (FESEM), UV–visible and photoluminescence spectroscopic techniques. Average particle size and crystalline phase were determined using the XRD technique. Surface nature and elemental composition were investigated by FESEM and EDX techniques, respectively. Optical parameters such as optical band gap, refractive index, and optical conductivity were estimated using UV–visible spectroscopic technique. The photoluminescence spectroscopic method determined PL emission peaks, CIE coordinates, and color purity.
