摘要

芴(Fl)衍生物是一种具有代表性的发光基团,因此,它们通常被安装在交替π共轭共聚物(P(Fl-Ar))中,作为可溶性聚合物发光体。许多研究人员专注于修改 P(Fl-Ar)衍生物中的组合芳基烯单元,以调整其光电特性;然而,含有在其 sp2 碳上带有官能团的芴单元的 P(Fl-Ar)衍生物仍然有限。在这里,我们通过使用氯化铝 (AlCl3) 进行阳极氯化,合成了包含 sp2 氯化芴单元的 P(Fl-Ar)衍生物。引入的氯原子会影响原始 P(Fl-Ar) 衍生物的光电特性。与前体 P(Fl-Ar)衍生物相比,氯化 P(Fl-Ar)衍生物的最大发射波长更长。

Post-functionalization of alternating π-conjugated copolymers containing fluorene moieties via anodic chlorination using AlCl3

Post-functionalization of alternating π-conjugated copolymers containing fluorene moieties via anodic chlorination using AlCl3

Fluorene (Fl) derivatives are representative emitting motifs; thus, they are often installed into alternating π-conjugated copolymers (P(Fl-Ar)) as soluble polymeric emitters. Many researchers have focused on modifying the combined arylene units in P(Fl-Ar) derivatives to tune their optoelectronic properties; however, P(Fl-Ar) derivatives that contain fluorene units with functional groups at their sp2 carbons remain limited. Here, we synthesize P(Fl-Ar) derivatives comprising sp2-chlorinated fluorene units via anodic chlorination using aluminum chloride (AlCl3). The introduced chlorine atoms affect the optoelectronic properties of the pristine P(Fl-Ar) derivatives. Compared with the precursor P(Fl-Ar) derivatives, chlorinated P(Fl-Ar) derivatives exhibit longer maximum emission wavelengths.
