Photochemistry of [Ru(tpy)(bpy)(L)]2+ complexes. A) Absorption spectra of 8 with irradiation (blue line, t=0, red line, t= 540 min). B) HPLC of 8 as a function of irradiation time. C) Absorption spectra of 9 with irradiation (blue line, t=0, red line, t= 100 min). D) Comparison of % conversion for 8 (red open □) and 9 (green open ○). The integrated area under the peaks from B) was used for % conversion of 8.
