In one embodiment, the invention provides a polymer comprising imidazole ring units having nitrogen at the 1 and 3 positions of the ring; a carbon at each of the 2, 4 and 5 positions of the ring; and radical substituents G1 and G2 carried at the 4 and 5 positions. G1 and G2 are each independently selected from cyano, substituents derived from cyano, and substituents which replace cyano. The polymers formed by at least two of the cyclic imidazole units. In another embodiment, the invention provides new imidazole compounds usable as monomers to form the polymers. In still another embodiment, the invention provides a method for using the polymers as a coupling/activator for synthon synthesis.
在一种实施例中,本发明提供了一种聚合物,其包括
咪唑环单元,该环单元在环的1和3位置具有氮原子;在环的2、4和5位置分别具有碳原子;以及在4和5位置携带的基团取代物G1和G2。G1和G2各自独立地选自
氰基、由
氰基衍生的取代基和替代
氰基的取代基。聚合物由至少两个环状
咪唑单元形成。在另一种实施例中,本发明提供了新的
咪唑化合物,可用作单体来形成聚合物。在另一种实施例中,本发明提供了一种使用聚合物作为
偶联剂/活化剂进行合成的方法。
