The structures of complexes. a cycTb-phEu and b cycEu-phTb, and c optimized geometry of the simplified 100-atom structure of cycTb-phEu as determined using the PBeh-3c functional24 with basis def2-SVP25 and effective core potentials for Tb and Eu26 in ORCA27 (refer to the SI for details). The charge-transfer nature of the d HOMO and e LUMO are shown
