由于其具有更高的可持续性,低毒性以及高能效的生产和回收利用,因此用于电池的有机基正极材料的兴趣日益浓厚。经历两次可逆氧化的有机p型化合物相对较少,但与经历单电子过程的分子相比,可以提供更高的比容量。我们在此介绍基于嗪(N-N键联的二亚胺)的聚合物,其特征是在与Li / Li +相比具有2.9和3.3 V的吸引电势下具有两个可逆氧化。交联且封端的基于嗪的聚合物在基于锂的半电池中提供了良好的循环稳定性,并且可用比容量为133 mA hg -1与高达100C速率的高速率性能配对。我们的研究介绍了作为有吸引力的阴极活性电池材料的杂志。

to phenyl group with methylene linkage (1 and 2a) are more reactive than the 2-halopyridinium salts with an ethylene group (3 and 4a). As expected, the 2-bromopyridinium salt linked to the phenyl group with ethylene linkage (4a) is more reactive than the 2-chloropyridinium salt with the ethylene group (3), which is different from the 2-halopyridinium salt with the methylene linkage. The transient intermediates

This study presents a method for synthesizing pyridine, quinoline, and isoquinoline ketones from 2-halogenated N-heterocycles under mild conditions. The use of H2O as both solvent and oxygen source makes the reaction environmentally friendly, with broad substrate applicability and high functional group tolerance.
