Abstract
Lanthanide (Ln) Metal Organic Frameworks (Ln: Sm or La-MOF) have been synthesized with chrysophenine ligand (CH) by solvothermal method. Furthermore, vibration spectroscopy, crystallography, morphology, and bandgap value of MOFs have also been studied. The FTIR result for Sm-MOF showed absorption peak shift of C=O stretching mode in DMF to the lower wavenumber means Sm-MOF were successfully formed and the FTIR result of La-MOF showed a sharp peak at 1571.27 cm-1 which confirmed the success in formation of La-MOF. XRD results for both of the MOF showed crystalline characteristic. Still, for La-MOF indicated higher crystallinity, it revealed from SEM/EDS result which showed uniform arrangement between La and chrysophenine. EDS data proved the composition of La, O, C, and S from chrysophenine in La-MOF. UV-DRS data showed the bandgap for Sm-MOF was 2.09 eV at 590 nm and La-MOF was 1.98 eV at 623 nm which means Ln-MOFs can be used as photocatalyst material under visible region.
