A new C, N-coordinated cyclometalated ruthenium complex Ru-1 containing 2-(2,4-difluoro) phenyl-4-pyridine carboxylie acid group was synthesized by coordination reactions and subsequent hydrolysis reaction. The products were characterized by I HNMR, UV-Vis and FI'-IR spectra. The results showed that 1HNMR and FT-IR spectra were well identical with the structure of Ru-1. The MLCT absorption of this complex was centered at 524 nm, red-shifted with nearly 50 nm after hydrolysis.
