The synthesis and characterization of several 2,9‐diarylphenanthrolines with anthracenyl substituents in the 2‐position is described. These compounds were used to prepare a series of homoleptic and heteroleptic bis(phenanthroline)copper(I) complexes, whose cyclic voltammetry, UV/Vis and fluorescence data are investigated. From PM3 semiempirical calculations it becomes clear that two different strategies can be applied to prepare clean heteroleptic complexes.
