Horseradish peroxidaze (HR-P)-catalyzed polymerization of 8-quinolinol proceeded regioselectively to give a soluble poly(quinolinol) (1). Reaction of 1 with Alq'(2)(Et) (q' = 2-methy-8-quinolinolato) provided a polymer-aluminum complex (2). 2 was photoluminescent both in solutions and in the solid state. Quantum yield (0) of the photoluminescence in the chloroform solution was 23%.
