Abstract


Metal - organic frameworks ( Metal- Organic Frameworks , MOFs) materials has unlimited network of highly regular structure , has a wide range of applications in many fields of electromagnetic, fluorescence , catalysis, gas storage and separation . 5 - isophthaloyl oxygen acetic acid (H3L) based on the principle of crystal engineering , ligand and metal ion reaction successfully synthesized by hydrothermal and solution method 11 metal - organic framework materials : [Mn ( HL) (phen) 2 (H2O)] · 7/4H2O (1) [Mn2 (HL) 2 (phen) 2 (H2O) 2] n · nH2O (2) [Mn (HL) (4,4 '-bipy ) 2 (H2O) 2] n · 2nH2O (3) [Mn4 (L) 2 (4,4 '-bipy) 2 (μ3-OH) 2 (H2O) 2] n · nH2O (4) [Mn3 (L) 2 (2,2 '-bipy) 2] n · 2nH2O (5) [Cd3 (L) 2 (2,2'-bipy) 2] n · 2nH2O (6) [Co4 (L) 2 (bime) (μ3 -OH) 2] n · nH2O (7) [Co4 (L) 2 (bimb) 2 (μ3-OH) 2] n · 3.5nH2O (8) [Ni4 (L) 2 (μ3-OH) 2 (H2O) 4] n · 3.85nH2O (9) [Ag2 (HL)] n (10) [Ce (HL) 2 (H2O) 4] n (11) by elemental analysis, IR spectroscopy , thermal gravimetric analysis of these compounds were preliminary characterized and determined the crystal structure of these complexes , fluorescent and magnetic properties of the particular complexes . Preliminary summary of the different flexible ligand method to construct MOFs its spatial structure of regulation of the law , to investigate the structure and properties of the part of the complex relationship and laws .
