((EtO2C)2-C(H)∧N∧N, 8), and the ruthenium complexes thereof, [Ru(EtO2C-tpy)(tpy)](PF6)2, 1a, [Ru(MeO2C-N∧C∧N)(tpy)](PF6), 2a, [Ru(EtO2C-C∧N∧N)(tpy)](PF6), 3a, and [Ru((MeO2C)2-C∧N∧N)(tpy)](PF6)2, 4a. In this series, cyclometalation results in a red shift as well as in a broadening of the electronic absorption features and is accompanied by a cathodic shift in the RuII/RuIII redox process. The complexes are
为了研究环金属化作为染料敏化太阳能电池新型敏化剂设计中通用工具的可行性,制备了一系列(环金属化)钌配合物。为此,我们制备了基于羧酸盐官能化的2,2':6',2''-吡啶(tpy)的三齿配体4'-乙氧羰基-2,2':6',2''-吡啶(EtO 2 C-N ∧ ñ ∧ N,5),甲基-3,5-二(2-吡啶基)苯甲酸甲酯(MEO 2 C-N ∧ C(H)∧ N,6),4-乙氧羰基-6-苯基-2,2'联吡啶(ETO 2 C-C(H)∧ ñ ∧ N,7),以及4,4'-双(甲氧基羰基)-6-苯基-2,2'-联吡啶((ETO 2 C)2 -C(H)∧ Ñ ∧ N,8),并且所述钌配合物,[茹(ETO 2 C-万吨)(TPY)](PF 6)2,1A,的[Ru(MEO 2 C-N ∧ ç ∧ N)(TPY)](PF 6),图2a,的[Ru(ETO 2 C-C ∧ ñ ∧ N)(TPY)](PF 6),3A,和的[Ru((MEO
