In the present work, after investigation about experimental approach in preparation of LDHs with large organic anions and characteristic studies of synthesized LDHs compounds with XRD –FT/IR-TGA -SEM-EDX- DRS and Photoluminescence spectroscopy(PL) analyses, these results are comprised with three level of computational studies involve molecular modeling, molecular dynamic simulation & quantum mechanic computation for confirmation of experiment results and proposition of exclusive structural properties: calculated X-ray diffraction pattern , proper aggregation, displacement stability of LDH contents, details of microscopic positions and distribution of nonbonding forces in LDHs environment through trajectory analysis file, and study of opto-physical activities: band structure analyses for band gap energies suggestion , electronic structure evaluates, and photo-optical investigation contain simulated edge absorption and appropriate aggregation make–photoluminescence efficiency, were explored. This kind of combined research can introduce Large Organic Acidic Anions –LDH (LOA-LDH) as advanced applied materials in broad range of nano technology.
