2,2′:6′,2′′-Terpyridine (tpy), 4′-(4-HOC6H4)-2,2′:6′,2′′-terpyridine (1), 4′-(4-MeOC6H4)-2,2′:6′,2′′-terpyridine (2), 4′-(4-MeSC6H4)-2,2′:6′,2′′-terpyridine (3), 4′-(4-H2NC6H4)-2,2′:6′,2′′-terpyridine (4) and 4′-(4-pyridyl)-2,2′:6′,2′′-terpyridine (4) act as N^N chelates in complexes of the type [Ir(C^N)2(N^N)][PF6] in which the cyclometallating ligand, C^N, is derived from 2-phenylpyridine (Hppy)
2,2':6',2''-吡啶(tpy),4'-(4-HOC 6 H 4)-2,2':6',2''-吡啶(1),4'-( 4-MeOC 6 H 4)-2,2':6',2''-吡啶(2),4'-(4-MeSC 6 H 4)-2,2':6',2''-吡啶(3),4'-(4-H 2 NC 6 H 4)-2,2':6',2''-叔吡啶(4)和4'-(4-吡啶基)-2,2':6 ',2''-吡啶(4)在[Ir(C ^ N)2(N ^ N)] [PF 6 ]类型的络合物中作为N ^ N螯合物起作用,其中环金属化配体C ^ N为衍生自2-苯基吡啶(Hppy)或3,5-二甲基-1-苯基-1H-吡唑(Hdmppz)。已经确定了八个络合物的单晶结构,并且在每个铱(III)络合物阳离子中,tpy单元的非配位吡啶环都与α-环糊精的环金属化环发生面对面的π堆积相互作用。相邻配体。[Ir(ppy)2(N ^ N)] +
