    供体-受体激发态寿命的配体控制
    摘要:
    对一系列二亚胺铂(II)二卤代碳烯烯(LPtL')进行的瞬态吸收和发射光谱研究表明,电荷分离的二氢gen茂烯→二亚胺电荷转移(LL'CT)激发态寿命显示出显着且非周期性地依赖于其杂原子二氢大麻酚配体。即,观察到的寿命与E供体的主量子数之间没有线性关系。用杂原子依赖性单重态-三重态(ST)的能隙和各向异性共价对ME(E = O,S,Se)键控制体系间交叉速率的贡献进行了解释。对于二氧戊烯配合物,1-O,O',E(T 2)> E(S 1),并且从S 1到S 0发生快速的非辐射衰减。然而,ë(T 2)≤ È(S 1)为重原子同系物,这提供了一种用于快速系统间交叉的机构。随后在3-S,S中内部转换为T 1产生了长寿命的发射三重态。具有硫族元素供体和5-Se,Se的两个LPtL'配合物的寿命介于1-O,O'和3-S,S之间。

    13C NMR chemical shifts of the donor carbons that bear the chalcogens and is further probed by S K-edge XAS. Remarkably, the NMR chemical shift differences also correlate with the spin–orbit matrix element that connects the triplet excited state with the ground state. Consequently, triplet LL′CT excited state lifetimes are proportional to both functions, demonstrating that specific ground state NMR chemical
    环戊烯(II)二亚胺配合物(L E,E ')Pt(bpy)的特征是电荷分离的二三烯供体(L E,E ')→二亚胺受体(bpy)配体配体的电荷转移(LL ``CT)激发态导致了它们有趣的光物理性质以及在太阳能转换应用中的潜在用途。尽管对这些络合物有浓厚的兴趣,但属元素对三重态LL'CT激发态寿命的依赖性仍然无法解释。三新(L E,E具有混合族元素供体的Pt(bpy)配合物表现出的衰减速率受自旋轨道介导的非辐射途径的支配,其幅度与混合族元素供体配体环境提供的各向异性价成正比。这种各向异性的共价在13带有族元素的供体碳的13 C NMR化学位移,并由S K-edge XAS进一步探测。值得注意的是,NMR化学位移差异还与将三重态激发态与基态相连的自旋轨道矩阵元素相关。因此,三重态LL'CT激发态寿命与两个函数成正比,表明特定的基态NMR化学位移可用于评估自旋轨道耦合对激发态寿命的贡献。

  • Sensitizing the Sensitizer: The Synthesis and Photophysical Study of Bodipy−Pt(II)(diimine)(dithiolate) Conjugates

    The dyads 3, 4, and 6, combining the Bodipy chromophore with a Pt(bpy)(bdt) (bpy = 2,2'-bipyridine, bdt = 1,2-benzenedithiolate, 3 and 6) or a Pt(bpy)(mnt) (mnt = maleonitriledithiolate, 4) moiety, have been synthesized and studied by UV-vis steady-state absorption, transient absorption, and emission spectroscopies and cyclic voltammetry. Comparison of the absorption spectra and cyclic voltammograms of dyads 3, 4, and 6 and those of their model compounds 1a, 2, 5, and 7 shows that the spectroscopic and electrochemical properties of the dyads are essentially the sum of their constituent chromophores, indicating negligible interaction of the constituent chromophores in the ground state. However, emission studies on 3 and 6 show a complete absence of both Bodipy-based fluorescence and the characteristic luminescence of the Pt(bpy)(bdt) unit. Dyad 4 shows a weak Pt(mnt)-based emission. Transient absorption studies show that excitation of the dyads into the Bodipy-based (1)pi pi* excited state is followed by singlet energy transfer (SEnT) to the Pt(dithiolate)-based (MML)-M-1'CT (mixed metal-ligand to ligand charge transfer) excited state (tau(3)(SEnT) = 0.6 ps, tau(4)(SEnT) = 0.5 ps, and tau(6)(SEnT) = 1.6 ps), which undergoes rapid intersystem crossing to the (MMLL)-M-3'CT state due to the heavy Pt(II) ion. The (MMLL)-M-3'CT state is then depopulated by triplet energy transfer (TEnT) to the low-lying Bodipy-based 3 pi pi* excited state (tau(3)(TEnT) = 8.2 ps, tau(4)(TEnT) = 5 ps, and tau(6)(TEnT) = 160 ps). The transition assignments are supported by TD-DFT calculations. Both energy-transfer processes are shown to proceed via a Dexter electron exchange mechanism. The much longer time constants for dyad 6 relative to 3 are attributed to the significantly poorer coupling and resonance of charge-separated species that are intermediates in the electron exchange process.
