A method of forming a crosslinked polymer comprising the step of reacting a crosslinkable group in the presence of a polymer, wherein:
the crosslinkable group comprises a core unit substituted with at least one crosslinkable unit of formula (I):
the crosslinkable group is bound to the polymer or is a crosslinkable compound mixed with the polymer;
Ar is aryl or heteroaryl which may be unsubstituted or substituted with one or more substituents independently selected from monovalent substituents and a divalent linking group linking the unit of formula (I) to the core unit; and
R is independently in each occurrence H, a monovalent substituent or a divalent linking group linking the unit of formula (I) to the core unit, with the proviso that at least one R is not H.
一种形成交联聚合物的方法,包括使可交联基团在聚合物存在下发生反应的步骤,其中:
可交联基团包括被至少一个式 (I) 可交联单元取代的核心单元:
可交联基团与聚合物结合或为与聚合物混合的可交联化合物;
Ar 是芳基或杂芳基,可以是未取代的,也可以被一个或多个取代基取代,这些取代基独立地选自于连接式(I)单元与核心单元的一价取代基和二价连接基;以及
R 在每次出现时均独立地为 H、一价取代基或连接式(I)单元与核心单元的二价连接基,但至少有一个 R 不是 H。
