Abstract
A series of fluorescence-containing indazole-fused ring systems were made with the support of g-C3N4/CuO as a catalyst via non-conventional (microwave) method. We have synthesized g-C3N4/CuO nanocomposites by mechanochemical process; further, its morphology and composition were studied using various instrumental techniques like Fourier transform infrared spectroscopy (FT-IR), X-ray powder diffraction (XRD), energy-dispersive X-ray spectroscopy (EDS), and transmission electron microscopy (TEM). Also, we have synthesized pyrimido[1, 2-b] indazole-4-yl methanol motifs without any solvent in single-step methodology utilizing microwave irradiation. The pyrimido[1, 2-b] indazole-4-yl methanol motifs were optimized using response surface methodology (RSM). This preparation was effortlessly accessible, and the overview of the substrates was authorized. The pyrimidoindazole core structures exhibit the most remarkable photo physical properties. Most of the pyrimidoindazole scaffold appears in solvatochromism and excited with blue–green fluorescence shift while using ethyl acetate as solvent. This result indicates that synthesized pyrimidoindazole core motifs have prodigious potential as fluorophores which will help us to study several applications.
