the dinuclear ruthenium complexes [(R3-tpy)Ru(N∧C∧N-tpy)Ru(tpy)]3+ (R = H ([5a]3+), CO2Me ([6a]3+), N∧C(H)∧N-tpy = 4′-(3,5-dipyridylphenyl)-2,2′:6′,2′′-terpyridine, tpy = 2,2′:6′,2′′-terpyridine) and [(R3-tpy)Ru(N′∧C∧N′-tpy)Ru(tpy)]3+ (R = H ([5b]3+), CO2Me ([6b]3+), N′∧C(H)∧N′-tpy = 4′-(3,5-di(4-tert-butylpyridyl)phenyl)-2,2′:6′,2′′-terpyridine) in a stepwise manner. The directional nature of the bridging
我们已经制备的双核钌络合物[(R 3 -tpy)的Ru(N ∧ ç ∧的N- TPY)的Ru(TPY)] 3+(R = H([ 5A ] 3+),CO 2我([ 6A ] 3+),N ∧ C(H)∧的N- TPY = 4' - (3,5-二dipyridylphenyl)-2,2':6',2'' -三联吡啶,TPY = 2,2':6', 2'' -三联吡啶)和[(R 3 -tpy)的Ru(N' ∧ ç ∧ N'-TPY)的Ru(TPY)] 3+(R = H([图5b ] 3+),CO 2我([ 6b ] 3+),N′C(H)∧N′ -tpy = 4′-(3,5-二(4-叔丁基吡啶基)苯基)-2,2′:6′,2′′-吡啶基)。桥接配体的方向性质可能在一侧进行环金属化,从而在所得双核络合物中引起较大的氧化还原不对称性。单电子氧化产生从[Ru(tpy 2)] 2+部分到环钌基团的强金属到金属的电荷转移跃迁,[
