A phenanthroline derivative, which has an aniline group, was synthesized by palladium catalyzed Suzuki cross coupling reactions. The aryl phosphine ligand, PPh3, showed higher activity than the alkyl phosphines, P(tBu)3 and PCy3, in the Suzuki couplings and provided the coupled product, 4-phenyl-7-(4′-amino-biphenyl-4-yl)-[1,10]phenanthroline (5), with 73% yield. Its ruthenium complex, bis(4,7-diphenyl-[1,10]phenanthroline){4-phenyl-7-(4′-amino-biphenyl-4-yl)-[1,10]phenanthroline} ruthenium(II) bis(hexafluorophosphate) (8), was synthesized under mild conditions. This complex showed a linear fluorescence intensity response between pH 3.5 and pH 8.5.
A phenanthroline derivative 5, which has an aniline group, was synthesized by palladium catalyzed Suzuki cross coupling reactions. The ligand, PPh3, gave the highest yield of the product in a K2CO3 base and THF/H2O solvent system. Its ruthenium complex 8 was synthesized under mild conditions. It showed a linear fluorescence intensity response between pH 3.5 and pH 8.5 .Figure optionsDownload as PowerPoint slide
