英文摘要	A green-emitting iridium(III) complex Ir(dfppy)(2)(cbphen) (dfppy = 2-(4',6'-difiuoro-phenyl)pyridine, cbphen = 4-carboxylate-phenanthroline) was synthesized and fully characterized. The single crystal data confirm its Ir(C boolean AND N)(2)(N boolean AND A) structure with the carboxylate group on phenanthroline stretching freely which could be able to combine with europium(III) ion. The complex was reacted with EuCl3 center dot 6H(2)O and Eu(TTA)(3)center dot 2H(2)O to provide bimetallic complexes. Through photophysical studies, characteristic emission from Eu-III ion was obtained, and meanwhile the green emission from iridium(III) center was almost quenched completely, suggesting this iridium(III) complex is a good sensitizer for Eu-III ions. It is well worth noticing that by introducing the iridium(III) complex as a chromophore, the excitation wavelength of Eu-III ion has been extended to the visible range (470 nm). Besides, due to the efficient energy transfer, the quantum yield of Ir-3-Eu was nearly equal to that of Eu(TTA)3 center dot 2H(2)O. (C) 2017 Elsevier B.V.
