linked to 1,4,8,11-tetraazacyclotetradecane (cyclam). Reaction of excess cyclam with 4′-[(4-bromomethyl)phenyl]-2,2′:2″,6′-terpyridine afforded the ligand 1-[4′-p-tolyl-(2,2′:6′,2″-terpyridyl)]-1,4,8,11-tetraazacyclotetradecane (L1) in which the tetraaza macrocycle was covalently attached to one benzyl-terpyridyl fragment. Under similar conditions reaction of cyclam with excess 4′-[(4-bromomethyl)phenyl]-2
已经设计了一种合成策略来制备新化合物,其中三联吡啶片段与 1,4,8,11-四氮杂环十四烷 (cyclam) 相连。过量环烷烃与 4'-[(4-溴甲基)苯基]-2,2':2",6'-三联吡啶反应得到配体 1-[4'-p-tolyl-(2,2':6' ,2”-三联吡啶)]-1,4,8,11-四氮杂环十四烷(L1),其中四氮杂大环共价连接到一个苄基-三联吡啶片段。在类似条件下,环丙烷与过量的 4'-[(4-溴甲基)苯基]-2,2':2",6'-三联吡啶反应得到四取代的环丙烷衍生物 1,4,8,11-[4'-对甲苯基-(2,2':6',2"-三联吡啶)]-1,4,8,11-四氮杂环十四烷 (L2)。多齿配体 L2 通过单晶 X 射线衍射技术进行晶体学表征。L1 与 [Ru(mtpy)Cl3] 反应得到杂配钌 (II) 配合物 [Ru(L1)(mtpy)][PF6]2 (mtpy = 4'-methyl-2
