In a typical preparation, 50 mg of Rh(III) starting material was dissolved in 32 mL of MeCN/water, 3:1,0.1 M in NaOH. To this mixture was added 1 equiv or more of, for example, 9,10-phenanthrenequinone to produce non-hindered control DNA photocleaving compounds, or 5,6-chrysenequinone (chrysi) or benzophenanzinediimine (phzi) to produce hindered intercalating compounds. During constant stirring, the reaction was allowed to progress for approximately 18 h at room temperature. After neutralization with dilute hydrochloric acid and addition of 500 mL of water, the reaction mixture was loaded onto a Sephadex SP-C25 ion exchange column equilibrated in 0.05 M MgCl2. The product was purified by elution with a gradient of 0.05-0.5 M MgCl2, and the orange product bands were collected. The fractions were concentrated on a Waters Sep-Pak 5 g C18 cartridge and washed with copious amounts of water. The metal complex was eluted from the cartridge with a minimum volume of 0.1% TFA in MeCN/water, 1:1, and lyophilized to dryness.
