Conducting Block Copolymers of Regioregular Poly(3‐hexylthiophene) and Poly(methacrylates): Electronic Materials with Variable Conductivities and Degrees of Interfibrillar Order
Abstract
Integration of regioregular poly(3‐hexylthiophene) in diblock copolymers with various poly(methacrylates) yielded electronic materials with variable conductivities and different types of nanoscale order. Solid state analysis of poly(3‐hexylthiophene)‐block‐poly(methyl methacrylate) and poly(3‐hexylthiophene)‐block‐poly(t‐butyl methacrylate) diblock copolymers revealed the presence of densely packed, locally parallel nanofibrils. By contrast, poly(3‐hexylthiophene)‐block‐poly(isobornyl methacrylate) copolymers containing bulkier isobornyl functional groups exhibited nanofibrillar morphology with isolated fibrils and no interfibrillar order.
