摘要

Conjugated polymers have received substantial attention attributable to their prospective usage in optoelectronic devices. Polyfluorene (PF), a classic blue light-emitting polymer, offers significant advantages over inorganic semiconductors thanks to their tunable band gaps and optoelectronic properties, which can be achieved through various polymerization techniques. This diversity opens the doors for tailoring various properties to suit the specifications of various optoelectronic applications. Therefore, in this review, the structure–property relationships of photoluminescence PF derivatives and their copolymers were discussed. Some in-depth views have been provided on the impact of molecular weight and alkyl side chains on the structure–property of PF derivatives. Meanwhile, some outlook has also been given to introducing functional groups into PF derivatives to modify the properties and emphasize the potential of copolymerization on advancing PF with desired properties. By comprehending the latest endeavours undertaken by researchers, diverse strategies could be employed to enhance the performance of PF-based optoelectronic devices, paving the way for the development of reliable and efficient optoelectronic devices.

Graphical Abstract
