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
Title polymeric complex(EPU Eu(Ⅲ)) was obtained from triisobutoxy euro pium Eu(C 3H 7O) 3 with electropolyurushiol in isobutyl alcohol.

The structure and property of the complex were characterized by FT IR, XPS, DMTA, AES, TG DTA and fluorescence spectrophotometry. The complex with Eu(Ⅲ) content reached up to 9 6% was insoluble in most organic solvents. Its electric resistance was 1 25×10 5 MΩ(that of EPU was 7 90×10 4 MΩ). Its T g and thermal resistance was considerably greater than that of EPU.展开更多
