| In recent years,more and more experts and scholars have attached great importan ce to the coordination chemistry of MOFs materials.The development of organic meta l complexes has promoted the coordination chemistry to a new field,greatly expandin g the field of coordination chemistry.As more complex valence bond and space struct ure of the organic metal complexes,so that they have very important application in th e biomedical,materials science,information energy and other fields.At present,resear ch in the field of coordination chemistry has penetrated into many other disciplines,w hich not only makes the coordination chemistry as many chemical branch channel and the intersection point,and deep into the physical,material,information and energy an d other fields,has attracted close attention of the researchers.In order to explore the efficient and novel metal complexes,a variety of 4-aminoacetophenone-based ligands were synthesized and then prepared with a variety of transition metals to prepare meta l complexes.Six single crystals were prepared by natural evaporation and gas phase diffusion using the synthesized ligands and different transition metal salts.The fluorescence prop erties of the ligands and complexes were investigated by fluorescence spectroscopy,an d the electrochemical properties of the complexes were analyzed preliminarily.Using the Gaussian 09 program,quantitatively calculated method was performed o n the synthesized ligands and complexes by DFT,according to the obtained quantitativ e results and the single crystal diffraction results,not only the experimental results we re verified but also the properties of the compounds were also predicted.We are adopt the way of natural volatilization and meteorological diffusion,get six single crystals,respectively HL1,HL2,[Zn(L2)2],[Cu(L3)2],[Zn(L4)2],HL5-Mn(II).These complexes were measured by using of X-ray single crystal diffraction analysis in purpose to determine their spatial configuration and composition.its crystallography data are as follows:HL1:Empirical formula,C17H17 Cl N2O2,Formula weight,316.77,Crystal system,Monoclinic,Space gyoup,P2(1)/c,Unit call dimensions: a = 17.789(2)?,b = 7.1127(7)?,c = 6.2885(6)?,?= 90°,? = 97.513(10)°,? = 90°,Z = 2,V = 788.84(14)?3,R1 = 0.0600,w R2 = 0.1651?HL2:Empirical formula,C16H16N2O3,Formula weight,284.31,Crystal system,Triclinic,Space group?P1,Unit call dimensions: a = 8.7904(7)?,b = 12.0808(11)?,c = 14.3999(11)?,? = 68.001(8)°,? = 81.114(6)°,? = 83.933(7)°,Z = 4,V = 1398.9(2)?3,R1 = 0.0666,w R2 = 0.1884;[Zn(L2)2] :Empirical formula,C32H30N4 Zn O6,Formula weight,631.97,Crystal system,Monoclinic,Space group,C2/c,Unit call dimensions: a = 20.8670?,b = 5.4304(3)?,c = 25.6526(15)?,? = 90°,? = 97.485(5)°,? = 90°,Z = 4,V = 2882.1(3)?3,R1 = 0.0495,w R2 = 0.1076;[Cu(L3)2] :Empirical formula,C40H34 Cu N4O4,Formula weight,698.25,Crystal system,Monoclinic,Space group,C2/c,Unit call dimensions: a = 27.435(2)?,b = 5.8930(3)?,c = 20.6752(14)?,? = 90°,? = 93.969(7)°,? = 90°,Z = 4,V = 3334.6(4)?3,R1 = 0.0618,w R2 = 0.1611;[Zn(L4)2]:Empirical formula,C34H34 Zn N4O6,Formula weight,659.76,Crystal system,Triclinic,Space group,?P1,Unit call dimensions: a = 13.9414(15)?,b = 17.6058(18)?,c = 18.278(2)?,? = 83.775(2)°,? = 76.523(1)°,? = 68.321(1)°,Z = 2,V = 4053.0(3)?3,R1 = 0.0700,w R2 = 0.1727?HL5-Mn(II): Empirical formula,C40H42Br4Cl4Mn4O16,Formula weight,659.764,Cryst al system,Triclinic,Space group,?P1,Unit call dimensions: a = 9.3724(9)?,b = 11.7876(16)?,c = 12.3994(18)?,? = 70.650(13)°,? = 75.462(10)°,? = 81.085(10)°,Z= 1,V =1247.1(3)?3,R1 = 0.0618,w R2 = 0.1201?... |
