Fig. 2: Characterization of coordinative interaction.
a 1H NMR titration with CoPc into a 0.20 mM DMF-d7 solution of IrQPY, highlighting some shifted proton signals. b DFT-calculated structures of IrQPY-CoPc and IrQPY-(CoPc)2. Counter anions are omitted for clarity. The Co-N bond lengths, bond orders, and c spin states of Co(II) are noted.
