  带有多达四个不同内消旋取代基的卟啉的合理合成。

  摘要：

  带有特定取代基图案的卟啉是仿生和材料化学中至关重要的组成部分。我们已开发出避免统计反应的方法，采用最少的色谱法，并提供最多克量的区域异构纯卟啉，带有多达四个不同内消旋取代基的预先指定图案。该方法基于几克数量的二吡咯甲烷的可用性。使用EtMgBr和酰氯对二吡咯甲烷进行二酰化的方法已经完善。已经开发出一种新的制备不对称二酰基二吡咯甲烷的方法，该方法涉及（1）用EtMgBr和吡啶硫基吡啶酯单酰化，然后（2）在与EtMgBr和酰氯反应时引入第二个酰基单元。通过制备多克量的带有各种取代基的二酰基二吡咯甲烷，已经检验了这些酰化方法的范围。用NaBH（4）在甲醇THF中将二酰基二吡咯甲烷还原为相应的二吡咯甲烷-二甲醇。卟啉的形成涉及二吡咯甲烷-二甲醇和二吡咯甲烷的酸催化缩合，然后用DDQ氧化。通过检查各种反应参数（溶剂，温度，酸，浓度，时间），可以确定最佳的缩合条件。确定的条件（2.5 mM反应物在室温下含有30

  环状六聚卟啉阵列的合理合成，用于研究自组装光收集系统。

  摘要：

  卟啉的两个新的环状六聚体阵列已经以合理，会聚的方式制备。每个环状六聚体中的卟啉通过联苯乙炔连接剂连接，提供直径约35 A的轮状阵列。一个阵列由5个锌（Zn）卟啉和1个游离碱（Fb）卟啉（环-Zn（5 ）FbU），而另一个则由两个锌卟啉和一个Fb卟啉的交替序列组成（cyclo-Zn（2）FbZn（2）FbU）。先前的合成采用单烧瓶模板指导的方法，并得到交替的Zn和Fb卟啉或所有Zn卟啉。更多样化的金属化图案对于操纵阵列中激发态能量的流动具有吸引力。每个阵列的合理合成采用了三个Pd介导的偶联反应，以及四个带有二乙炔基，二碘，溴/碘或碘/乙炔基的四芳基卟啉构件。通过卟啉五聚体+卟啉单体的反应或两个卟啉三聚体的连接来实现产生环状六聚体的最终闭环。在存在三吡啶基模板的情况下，5 +1和3 + 3反应的产率为10％至13％。在没有模板的情况下的5 +1反应以3.5％的产率进行，从而确定了结构对环状六聚体形成的贡献。3

  We present the design of molecular materials for ultimate use in solid-state solar cells. The molecular materials are semi-rigid oligomeric rods of defined length with metalloporphyrins in the backbone and a carboxy group at one end for attachment to a surface. The rods are designed to absorb visible light, and then undergo excited-state energy transfer and ground-state hole transfer in opposite directions along the length of the rod. The rational synthesis of the multiporphyrin arrays relies on joining porphyrin building blocks in an efficient and controlled manner. Several porphyrin building blocks have been synthesized that bear bromophenyl, iodophenyl, trimethylsilylethynylphenyl and/or ethynylphenyl substituents for use in a copper-free Sonogashira reaction using Pd2(dba)3 and P(o-tol)3. Competition experiments performed on equimolar quantities of an iodo-porphyrin and a bromo-porphyrin with an ethynyl-porphyrin show iodo + ethyne coupling with a low amount (35 °C) or undetectable amount (22 °C) of bromo + ethyne coupling. Efficient coupling of bromo-porphyrins with ethynyl-porphyrins was achieved using the same copper-free Sonogashira reaction conditions at higher temperature (50 °C or 80 °C). These findings allow successive coupling reactions to be achieved using substrates bearing iodo and bromo synthetic handles. Thus, a porphyrin-based tetrad (or pentad) was synthesized with a final convergent coupling of a bromo-substituted dyad (or triad) and an ethynyl-substituted dyad. A porphyrin triad was prepared by sequential iodo + ethyne coupling reactions. The triad, tetrad, and pentad each are comprised of a terminal magnesium porphyrin bearing one carboxy group (for surface attachment) and two pentafluorophenyl groups; the remaining porphyrins in each array are present as the zinc chelate. Electrochemical characterization of benchmark porphyrins indicates the presence of the desired electrochemical gradient for hole hopping in the arrays. Static absorption data indicate that the arrays are weakly coupled, while static fluorescence data indicate that the excited-state energy flows in high yield to the terminal magnesium porphyrin. Time-resolved spectroscopic analysis leads to rate constants in THF of (9 ps)−1, (15 ps)−1, and (30 ps)−1 for ZnMg dyad 20, Zn2Mg triad 13, and Zn3Mg tetrad 15, respectively, and quantum efficiencies ≥99% for energy flow to the magnesium porphyrin in each case. These design and synthesis strategies should be useful for the construction of materials for molecular-based solar cells.

  我们介绍了用于固态太阳能电池的终极应用的分子材料的设计。这些分子材料是具有特定长度的半刚性寡聚棒，其骨架中含有金属卟啉，一端带有羧基以附着于表面。这些棒设计用于吸收可见光，然后在棒的长度上沿着相反方向进行激发态能量传递和基态空穴传递。多卟啉阵列的合理合成依赖于以高效且受控的方式连接卟啉构建块。已经合成了几种带有溴苯基、碘苯基、三甲基硅乙炔基苯基和/或乙炔基苯基的卟啉构建块，用于在无铜Sonogashira反应中使用Pd2(dba)3和P(o-tol)3。在等摩尔量的碘卟啉和溴卟啉与乙炔基卟啉的竞争实验中，碘+乙炔偶联在低量（35°C）或无法检测量（22°C）下，而溴+乙炔偶联未发生。在更高温度（50°C或80°C）下，使用相同的无铜Sonogashira反应条件实现了溴卟啉与乙炔基卟啉的高效偶联。这些发现允许使用带有碘和溴合成柄的底物实现连续偶联反应。因此，通过最终的汇聚偶联反应合成具有溴取代的双体（或三体）和乙炔基取代的双体的基于卟啉的四体（或五体）。通过连续的碘+乙炔偶联反应制备了卟啉三体。三体、四体和五体各自由一个末端带有羧基（用于表面附着）和两个五氟苯基的镁卟啉组成；每个阵列中的其余卟啉作为锌螯合物存在。基准卟啉的电化学表征显示了阵列中空穴跳跃所需的电化学梯度的存在。静态吸收数据显示阵列是弱耦合的，而静态荧光数据显示激发态能量高效流向末端镁卟啉。时间分辨光谱分析得出了THF中的速率常数，分别为ZnMg双体20的(9 ps)−1、Zn2Mg三体13的(15 ps)−1和Zn3Mg四体15的(30 ps)−1，且每次能量流向镁卟啉的量子效率≥99%。这些设计和合成策略应有助于构建基于分子的太阳能电池材料。
• Synthesis of perylene–porphyrin building blocks and rod-like oligomers for light-harvesting applications

  We present the synthesis of four perylene–porphyrin building blocks for use in Glaser, Sonogashira, or Suzuki polymerizations. The building blocks bear synthetic handles (4-ethynylphenyl, 4-iodophenyl, bromo) at the trans (5,15) meso-positions of a zinc porphyrin and contain two or four perylene-monoimide dyes attached at the 3,5-positions of the non-linking meso-aryl rings of the porphyrin. Each perylene-monoimide bears three 4-tert-butylphenoxy substituents (at the 1-, 6-, and 9-positions) and two isopropyl groups (on the N-aryl unit) for increased solubility. In each case the intervening linker is a diarylethyne unit that bridges the N-imide position of the perylene and the meso-position of the porphyrin. The perylene–porphyrin building blocks were prepared by (1) reaction of a diperylene-dipyrromethane with an aldehyde yielding a trans-A2B2-porphyrin, (2) reaction of a diperylene-aldehyde with a dipyrromethane yielding a trans-A2B2-porphyrin, and (3) reaction of a diperylene-dipyrromethane with a dipyrromethane-dicarbinol yielding a trans-AB2C-porphyrin or ABCD-porphyrin. The building blocks were subjected to Glaser, Sonogashira, or Suzuki coupling conditions in an effort to prepare oligomers containing porphyrins joined via 4,4′-diphenylbutadiyne (dpb), 4,4′-diphenylethyne (dpe), or 1,4-phenylene linkers (p), respectively. Each porphyrin in the backbone bears two or four pendant perylene-monoimide dyes. The Glaser and Sonogashira reactions afforded a distribution of oligomers, whereas the Suzuki reaction was unsuccessful. The oligomers were soluble in solvents such as toluene, THF, or CHCl3 enabling routine handling. The use of perylenes results in (1) increased light-harvesting efficiency particularly in the green spectral region where porphyrins are relatively transparent and (2) greater solubility than is achieved with the use of porphyrins alone. The soluble perylene–porphyrin oligomers are attractive for use as light-harvesting materials in molecular-based solar cells.

  我们展示了四种用于Glaser、Sonogashira或Suzuki聚合的苝–卟啉构件的合成。这些构件在锌卟啉的反式（5,15）美索位点上带有合成手柄（4-乙炔基苯基、4-碘苯基、溴）并在卟啉的非连接美索芳香环的3,5位上附有两个或四个苝单酰亚胺染料。每个苝单酰亚胺上都有三个4-叔丁基苯氧基取代基（位于1、6和9位）和两个异丙基（在N-芳基单元上），以提高溶解度。在每种情况下，介导链是一个二芳基乙炔单元，连接苝的N-酰亚胺位和卟啉的美索位。苝–卟啉构件的制备方法包括：（1）将二苝-二吡咯烷与醛反应生成反式A2B2-卟啉；（2）将二苝-醛与二吡咯烷反应生成反式A2B2-卟啉；（3）将二苝-二吡咯烷与二吡咯烷-二醇反应生成反式AB2C-卟啉或ABCD-卟啉。这些构件在Glaser、Sonogashira或Suzuki偶联条件下进行处理，以便制备包含通过4,4'-二苯基丁炔（dpb）、4,4'-二苯乙炔（dpe）或1,4-苯基链接（p）连接的卟啉的低聚物。骨架中的每个卟啉附有两个或四个悬挂的苝单酰亚胺染料。Glaser和Sonogashira反应产生了低聚物的分布，而Suzuki反应则未成功。所制备的低聚物在如甲苯、THF或CHCl3等溶剂中可溶，便于常规操作。使用苝可以导致（1）在卟啉相对透明的绿色光谱区域内，光捕获效率的提高；（2）相比仅使用卟啉，获得更高的溶解度。这些可溶的苝–卟啉低聚物在基于分子的太阳能电池中作为光捕获材料具有吸引力。
