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

Its structure was elucidated with elementary analysis, IR and 1 HNMR, and their properties relevant to liquid crystal were determined by using DSC and texture. The phase transition temperature K64M244I.It was found that the compound has the opticity. The specific rotation [α] 25 D=+25.86 (C, 0.58, CHCl 3).展开更多
A novel compound of pyrazoline derivative,3-(4-methoxyphenyl)-5-[4-(1,1-dimethylethylphenyl)]-4,5-dihydro-1-phenyl 1H-Pyrazole(PYZ)has been synthesized.It has a good photoluminescence property and could give blue fluo...A novel compound of pyrazoline derivative,3-(4-methoxyphenyl)-5-[4-(1,1-dimethylethylphenyl)]-4,5-dihydro-1-phenyl 1H-Pyrazole(PYZ)has been synthesized.It has a good photoluminescence property and could give blue fluorescence.Four devices have been fabricated to study the carrier-transporting and electroluminescence properties of PYZ.The results indicate that PYZ is a good blue electroluminescent material.The emission peak is observed at 449nm and the half bandwidth is about 80nm,showing that it could emit pure blue light.As to carrier-transporting property,PYZ is found to have electron-transporting ability besides its excellent hole transporting ability.展开更多
