A novel chelate Eu(TTA) 2(PMTBBP)Phen, which contained ligand 1 pheny 3 methyl 4 (4 t butylbenzoyl) 5 pyrazolone(HPMTBBP), 4,4,4 trifluro 1 (2 thienyl) 1,3 butandione(HTTA) and phenanthroline(Phen), was synthesized....A novel chelate Eu(TTA) 2(PMTBBP)Phen, which contained ligand 1 pheny 3 methyl 4 (4 t butylbenzoyl) 5 pyrazolone(HPMTBBP), 4,4,4 trifluro 1 (2 thienyl) 1,3 butandione(HTTA) and phenanthroline(Phen), was synthesized. Its chemical structure was elucidated by IR, UV, 1H NMR, MS, DSC and elementary analysis. The influence of acylpyrazolone on fluorescent intensity of the new chelate was studied. The results showed that Eu(TTA) 2(PMTBBP)Phen had more excellent PL properties and better film formation than that of Eu(TTA) 3Phen. [WT5HZ]展开更多

The crystal belongs to monoclinic system, P 2 1/ c (No.14) space group with a =0.978 1(2) nm, b =0.733 8(1) nm , c =2.962 9(6) nm, β =91.81(3)°, V =0.212 6(1) nm 3, Z =4, M =606.31, D x=1.895 g·cm -3 , μ =1.382 1 mm -1 , F (000)=1 228, R =0.035 and R w=0.041 for 2 802 unique reflections. The complex anion [In Ⅲ(Hdtpa)] - has a pseudo monocapped trigonal prismatic seven coordination structure in which the seven coordinate atoms, three N and four O atoms, are all from a ligand dtpa. In addition, it can be seen that the complex anion [In Ⅲ(Hdtpa)] - can furnish a free carboxyl group(—CH 2COOH) being used for molecular embellishment to form the target diagnosis and treat drug of anticancer.
