Several dimeric 1,2-bis (2,2′-bipyridinyl)ethane (1,2,6,7, and 9 and 1,2-bis(1,10-phenanthrolinyl)) ethane (3,4, and 5) ligands have been synthesized in high yield by oxidative coupling of the corresponding monomeric methylene carbanions using as oxidating agents Br2, I2, and 1,2-dibromoethane. The structure of the compounds obtained from three tetramethyl-2,2′-bipyridines and one tetramethyl-1,10-phenanthroline
几种二聚物1,2-双(2,2'-联吡啶基)乙烷(1,2,6,7和9和1,2-双(1,10-菲咯啉基))乙烷(3,4和5)通过使用Br 2,I 2和1,2-二溴乙烷作为氧化剂,通过氧化相应的单体亚甲基碳负离子,可以高产率地合成配体。由3个四甲基-2,2'-联吡啶和1个四甲基-1,10-菲咯啉获得的化合物的结构已基于其1 H-NMR谱进行了指定。报道了这些新的配体的电子吸收和发射性质。它们显示出强烈的荧光光谱。
