Abstract
We have investigated the chiroptical properties of novel PPEs containing chiral side chains. The synthesis of poly(2,5-bis[2-(~)-methylbutoxy]- 1,4-~henyleneethynylene) Heck-type aryl-aryl cross coupling (Mn (BMB-PPE) was achieved in a = 10000, OD = 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.
