The Synthesis, Crystal Structure And Properties Investigations Of （Dihydro） Anthrancene Compounds; The Synthesis, Investigations On Rectangle WO₃ Nano Materials

Four organic ligands of（dihydro）anthrancene derivation and one pyredines ligand have been synthesized and characterized by elemental analysis,IR spectra and UVspectra.The five ligands are 2-（2,3,6,7-tetramethoxy-9-（pyredin-2-yl）-9,10-dihyd roanthracen-10-yl）pyridine（L_a）,2-（2,3,6,7-tetramethoxy-9-（pyredin-2-yl）anthracen-10 -yl）pyridine（L_b）,4-（2,3,6,7-tetramethoxy-9-（pyredin-4-yl）-9,10-dihydro anthracen-10 -yl）pyridine（L_c）,4-（2,3,6,7-tetramethoxy-9-（pyredin-4-yl）anthracen-10-yl）pyridine（L_d） 4-[（3,4-Dimehtoxy-cyclohexa-2,4-dienyl）-（3,4-dimethoxy-phenyl）-mehtyl]-pyridine （L_e）.Four single crystal structures of the ligands[（L_a）（L_c）（L_d）（L_e）]have been determined.And the fluorescence properties have been studied,（Lb）,（Ld）,（Le）show good fluorescence properties.Many metal complexes and supermolecule were synthesized via the reaction of the ligands with transition metal,and some of them are characterized by elemental analysis,IR spectra and UV spectra.The crystal structure for[Cu（L_a）NO₃]（f）, [（La）₂（CuCl₄）（CuCl₆）（HCl）₂（H₂O）₂（g）,[（La）NO₃]（h）were obtained.In complex（f）, copper ion（I） is three-coordinated,we analyse its structure and investigate its two-photon process,the two photon absorption cross sectionσ=5969.784GM.We also investigate its thermal stability.In complex（g）,it contain two ligand（L_a） molecular,we investigate its thermal stability.（h） is supermolecule,the flulrescence properties of（h） were investigated.We research hierarchical self-assembly of amphiphilic molecules TPDP and TPAP in aqueous solution and in two-phase boundary as while via controling differdnt solvent,temperature and proportion.We take the time-lapse optical micrographs of growth for the hierarchical self-assembly of amphiphilic molecules and take pictures of the pricky superstructures using field-emission scanning electron microscopy.
