我们报告了新型交替共聚物的合成的类型A-alt-B,其中A是一个二烷基芴单元和B是一个芳香族部分的单元,它是变化的,以改变前沿能级的位置,特别是我们发现,B单元噻吩S,S-二氧化物是特别有效的,在增加聚合物的电子亲和力和电离电位。
We report the synthesis of novel alternating copolymers of the kind A-alt-B, where A is a dialkylfluorene unit and B is an aromatic moiety unit which is varied in order to change the position of the frontier energy levels; in particular we find that the B unit thiophene S,S-dioxide is particularly effective at increasing the polymer electron affinity and ionisation potential.
