2,9‐Dimethyl‐1,10‐phenanthroline (neocuproine, 1 ) has been attached to dendritic structures through its 5‐position providing a trimer 7 and the hexamers 11 and 12 . The copper‐binding capability of the hexamer 12 has been studied, and the 6:1 complex has been used to catalyze the Cu + ‐promoted substitution of an iodoarene 14 to give an aryl ether 15 .
