A luminescent tetranuclear ruthenium(ii) complex as a tracking non-viral gene vector
Instruments Microanalysis (C, H, and N) was carried out with a Perkin-Elmer 240Q elemental analyzer. 1 H NMR spectra were recorded on a Varian-500 spectrometer at 25 o C. All chemical shifts are given relative to tetramethylsilane (TMS). Electrospray mass spectra (ES-MS) were recorded on a LCQ system (Finnigan MAT, USA). UV-Vis spectra were recorded on a Perkin-Elmer Lambda 850 spectrophotometer. Emission spectra were recorded on a PerkineElmer LS 55 spectrofluorophotometer at room temperature.doi:10.1039/c2cc37896e pmid:23235506 fatcat:7kstvaxqaragfk4drtrphvzdta
