실험 절차

3.05 mM of the 4-di(2-thienyl)-1,4-butanedione obtained from Step 1 described above, 3.03 mM of 1,10-phenanthroline-5-amine, and 5.4 mM of p-toluene sulfonic acid were dissolved in toluene, and then refluxed under a nitrogen current for 4 days. The refluxed mixture was cooled to room temperature, and then toluene was removed from the mixture. The remaining material was dissolved in 5 ml of 99.8% dichloromethane solution, and eluted by using a silica column to obtain 5-di(thiophen-2-yl)-1H-pyrrol-1-yl)-1,10-phenanthroline. The yield was 85%, and the structure was confirmed by using 1H NMR. The spectroscopic data thereof is as follows:
