Summary: Hole transporting poly( N ‐vinylcarbazole) copolymers with phenylazomethine dendron units acting as metal ligation sites were synthesized. These polymers possess both hole‐transport and metal‐collecting units with simple σ ‐bond linkages. Complexation in the phenylazomethine dendron unit within these copolymers by SnCl 2 has been successfully observed by the change in the UV‐vis spectra. The complexation changes the HOMO/LUMO energy gap that results in a spectral red‐shift. Using copolymers as a hole‐transport layer, only complexation with metal ions leads to an enhanced maximum luminescence. Such a complexation results in a high electroluminescence efficiency because the p ‐type‐doped structure acts as the hole‐transport layer.Copolymerization for the preparation of DPAG n ( x )‐Cbz( y ).
