基于芴衍生物的D-A化合物及其共聚物的研究进展

芴衍生物具有吸电子性,作为电子受体在D-A共聚体的研究中备受关注。在D-A共聚体中,π-电子供体和π-电子受体通过π键或σ键交替连接,其共平面的共轭结构有利于降低体系的能隙;以芴、芴酮、9-二氰基亚甲基芴衍生物为电子受体单元的推拉型(D-A型)化合物和共聚物,具有优异的光电性能、电子传输性能、较好的电子和空穴迁移率及在空气中极好的稳定性等。主要对基于芴、芴酮、9-二氰基亚甲基芴的D-A化合物及其D-A共聚物的最新研究进展做简要综述。

Research progress of D-A Compounds and Copolymers Based on Fluorene Derivatives

Fluorene derivatives have electron withdrawing properties and have attracted much attention by acting as electron acceptors in D-A copolymers.In D-A copolymers,π-electron donors and π-electron acceptors are connected by π-bond or σ-bond alternately,the planar conjugated structure is conducive to reduce the system energy gap; Push-pull(D-A) type compounds and polymers with fluorene derivatives such as fluorene,fluorenone and 9-dicyanomethylene as electron acceptor units have showed excellently photoelectric properties,electron transport properties,good electron and hole migration rate and excellent stability.In this paper the recent research progress of fluorene derivatives including 9-dicyanomethylene fluorene as well as their D-A compounds and copolymers was briefly summarized.
