This paper describes the facile synthesis of a hyperbranched poly(aryl ester) that possesses a number of porphyrin units within its globular structure. The simple procedure utilizes commercially available starting materials which after fractionation generate a series of polymers with molecular weights between 4500 and 30 000 Da. The number of porphyrins increased with molecular weight with the largest polymer containing similar to 6 porphyrins. Further analysis revealed a linear relationship between the number of incorporated porphyrins and molecular weight.
