  The invention relates to 2,7-substituted-9-substituted fluorenes and 9-substituted fluorene oligomers and polymers. The fluorenes, oligomers and polymers are substituted at the 9-position with two hydrocarbyl moieties which may optionally contain one or more of sulfur, nitrogen, oxygen, phosphorous or silicon heteroatoms; a C 5-20 ring structure formed with the 9-carbon on the fluorene ring or a C 4-20 ring structure formed with the 9-carbon containing one or more heteroatoms of sulfur, nitrogen or oxygen; or a hydrocarbylidene moiety. In one embodiment, the fluorenes are substituted at the 2- and 7-positions with aryl moieties which may further be substituted with moieties which are capable of crosslinking or chain extension or a trialkylsiloxy moiety. The fluorene polymers and oligomers may be substituted at the 2- and 7′-positions. The monomer units of the fluorene oligomers and polymers are bound to one another at the 2- and 7′-positions. The 2,7′-aryl-9-substituted fluorene oligomers and polymers may be further reacted with one another to form higher molecular weight polymers by causing the optional moieties on the terminal 2,7′-aryl moieties, which are capable of crosslinking or chain extension, to undergo chain extension or crosslinking. Also disclosed are processes for preparing the disclosed compounds.

  本发明涉及2,7-取代-9-取代芴和9-取代芴寡聚物和聚合物。这些芴，寡聚物和聚合物在9位取代有两个烃基官能团，该官能团可以选用一个或多个硫、氮、氧、磷或硅杂原子中的一个或多个; 由芴环上的9碳形成的C5-20环结构或由含有一个或多个硫、氮或氧杂原子的9碳形成的C4-20环结构; 或一个烃基亚甲基官能团。在一种实施例中，芴在2-位和7-位上取代芳基官能团，该芳基官能团还可以取代具有交联或链延伸能力的官能团或三烷氧基官能团。芴聚合物和寡聚物可以在2-位和7'-位上取代。芴寡聚物和聚合物的单体单元在2-位和7'-位上相互结合。2,7'-芳基-9-取代芴寡聚物和聚合物可以通过使具有交联或链延伸能力的末端2,7'-芳基官能团上的可选官能团发生链延伸或交联作用而进一步彼此反应形成更高的分子量聚合物。此外还公开了制备所述化合物的方法。
