The Name is Diphenyl oxide. Through research, I have a further understanding and discovery of 101-84-8. SDS of cas: 101-84-8
Three binuclear Eu3+ helicates, [Eu2(OBTA)3(H2O)3(CH3COCH3)]center dot 1.5CH3COCH3 center dot H2O (1), [Eu2(OBTA)3(Bpy)2]center dot 2CH3COCH3 center dot CH2Cl2 (2), [Eu2(OBTA)3(Phen)2]center dot 2CH3COCH3 (3) based a new bis-beta-diketone, 4,4 ‘-bis(4,4,4-trifluoro-1,3-butanedione) diphenyl ether (OBTA) was prepared in order to insight into the effects of complexes structure on Ln3+ ion emission properties. X-ray single crystal diffraction analyses confirmed the formation of binuclear triple-stranded helicates. The introduction of different ancillaries (Solvent molecular H2O and CH3COCH3; 2,2 ‘-bipyridine, Bpy and 1,10-phenanthroline, Phen) to helicates regulate the coordination environments around Eu3+ ions, and lead to the obvious variations of photophysical properties. Combination the structural analyses and photophysical experiment results, the significance of spatial tension of helicate is emphasized.
Bye, fridends, I hope you can learn more about C12H10O, If you have any questions, you can browse other blog as well. See you lster.. SDS of cas: 101-84-8
