We have investigated the chiroptical properties of novel PPEs containing chiral side chains. The synthesis of poly(2,5‐bis[2‐( S )‐methylbutoxy]‐1,4‐phenyleneethynylene) (BMB‐PPE) was achieved in a Heck‐type aryl‐aryl cross coupling ( M n = 10 000, D p = 40). The very good solubility of BMB‐PPE allows for a detailed study of its chiroptical properties. Our studies demonstrate that the bisignated CD spectra of BMB‐PPE are associated with an intermolecular aggregation phenomena.
