  摘要：

  带有0、1、2和3代树突状吩噻嗪部分的4,4'-二甲基联吡啶配体封端的钌配位化合物家族显示出尺寸依赖性的电化学性质以及结构依赖性的吸收和发光光谱。发射量子产率，光致发光衰减动力学和瞬态吸收光谱随树状分子的大小和复杂性在亚纳秒至毫秒的时间尺度上变化很大。所有配合物均表现出微秒寿命的最低价的金属-配体电荷转移激发态。与未取代的母体相比，发光光谱变宽了，大的树枝状簇的发射量子产率降低了2到5倍。尽管观察到的衰减动力学很复杂，但一个瞬变却以纳秒级迅速衰减，第二中间产物在几十纳秒的时间范围内没有衰减。瞬态吸收测量显示，由于金属到配体的电荷转移瞬变以及分离的吩噻嗪和钌联吡啶基部分的瞬态吸收位移，高基态吸收率区域中的基态漂白。

• Charge Separation in Donor-Chromophore-Acceptor Assemblies: Linkage and Driving Force Dependence of Photoinduced Electron Transfers

  A series of covalently linked Ru(bipyridine)(3)-donor-acceptor complexes was prepared where the donor-to-chromophore and acceptor-to-chromophore methylene chain lengths were varied. Time-resolved absorption studies were performed to elucidate intramolecular electron transfer rates. The electron donor in the above series is a phenothiazine moiety Linked to a bipyridine by a (-CH2-)(p), p = 3-8 chain, and the electron acceptor is an N,N'-diquaternary-2,2'-bipyridinium moiety Linked to a bipyridine by a (-CH2-)(m), m = 2, 3, 4 chain. Oxidative quenching of the Ru(bipyridine)(3) metal-to-ligand charge transfer (MLCT) state followed by phenothiazine-to-ruthenium electron transfer resulted in a long-lived charge-separated state. A wavelength-dependent excitation resulted in a slowly decaying absorption which is assigned to the excited-state phenothiazine. The magnitude of this component in the transient absorption serves as an internal standard for determining relative quantum yield for formation of the charge-separated state. Marcus inverted region behavior was observed in back electron transfer. Rate constants for electron transfer from phenothiazine to Ru(III) decreased as the length of the bridging chain increased from p = 4 to 8. Chain length independence of the back electron transfer rate in the series of complexes with varied chromophore-acceptor distances (m = 2, 3, and 4) suggests the formation of an association complex during oxidative quenching of MLCT state and argues against a sigma-bond superexchange pathway for back electron transfer.
