New Macrocyclic Bis-1,10-phenanthroline-2,9-dicarboxamides. Synthesis and Stereodynamics in Solution

New macrocyclic 1,10-phenanthroline-2,9-dicarboxamide derivatives containing two phenanthroline cores were synthesized, and their structure was confirmed by NMR spectroscopy and other methods. The new macrocyclic phenanthrolines showed a complex stereodynamic behavior in solution, which was studied by 1 H NMR spectroscopy at different temperatures.
