Abstract

Two new copper-based metal organic frame work (Cu-MOF21 and CU-MOF-22) was synthesized using bromo malonaldehyde and terephthalic an amino terephthalic acid. They synthesized CU-MOFs were characterized by FT-IR, UV-Visible spectroscopy. The XRD diffraction pattern indicated 2 θ at 17.3° and 26.8°. The Tauc’s method was employed to calculate the band gap of Cu-MOFs and was found that Cu-MOFS-21 exhibited 3.14 eV and Cu-MOF-22 with average bandgap energy at 3.61 eV attributed to the ligand-metal charge transfer. The results indicate that both Cu-MOFs can be further modified by suitable dopants to enhance the conductivity and reduce the band gap energy. Keywords: Metal organic frameworks, Copper metal, Bandgap energy, photoluminescence,
