Incorporation of benzothiadiazole into the backbone of 1,2,5,6-naphthalenediimide based copolymers, enabling much improved film crystallinity and charge carrier mobility

By incorporating benzothiadiazole units into the main chain of 1,2,5,6-naphthalenediimide based copolymers, we report herein a new copolymer with much improved film crystallinity and charge carrier mobility.
