  A versatile synthetic strategy based on the use of a non-peripherally substituted dihydroxysilicon phthalocyanine and dihydroxygermanium octaethylporphyrin has permitted controlled construction of heterodyads that absorb across the whole visible spectrum; the same phthalocyanine also reacts with chlorosubphthalocyanine to form a Si–O–B linked dyad and triad.

  The article reviews the exploitation of the serendipitous discovery that dihydroxysilicon 1,4,8,11,15,18,22,25-octakis(hexyl)phthalocyanine 1 reacts at one face only to form a μ-oxo linked bond to dichlorosilicon phthalocyanine. Reaction of 1 with dihydroxysilicon octaethylporphyrin led to an unstable μ-oxo linked Pc-O-Pn heteroligand dyad that could not be isolated. However, reaction with dihydroxygermanium octaethylporphyrin gave a stable dyad that showed substantial broad band absorption attributable to exciton effects. A small amount of the μ-oxo linked homo dyad formed by self-condensation of dihydroxygermanium octaethylporphyrin was detected by MALDI-TOF mass spectrometry but was not isolated. Reaction of 1 with chloroboron subphthalocyanine afforded the stable Pc-O-SubPc heterodyad as the main product and the SubPc-O-Pc-O-SubPc triad as a minor side product. Both gave absorption spectra that showed the main features of the ligands present, implying limited exciton coupling. A further reaction of 1 with axial-hydroxy, axial-methyl silicon phthalocyanine provided a key Pc-O-Pc′ dyad that proved to be an ideal intermediate for developing a synthetic strategy to access a series of hetero-metalloid/hetero-ligand Pc-O-Pc′-O-Pn triads. X-ray structural data for examples of these arrays are discussed. A feature of the triad compounds is their very broad band absorption spectra that extends from the UV through the visible region to near IR wavelengths.

  文章回顾了利用偶然发现二羟基硅 1,4,8,11,15,18,22,25-八(己基)酞菁 1 仅在一个面上与二氯硅酞菁反应形成一个 μ-oxo 链接键的情况。1 与二羟基硅八乙基卟啉反应后，产生了不稳定的 μ-oxo 连接的 Pc-O-Pn 杂配体二元，无法分离。然而，与二羟基锗八乙基卟啉反应后，得到了一种稳定的二元化合物，该化合物显示出大量可归因于激子效应的宽带吸收。通过 MALDI-TOF 质谱法检测到了少量由二羟基八乙基卟啉锗自缩合形成的 μ-oxo 链接同族二元化合物，但没有分离出来。1 与氯硼亚酞菁反应生成了稳定的 Pc-O-SubPc 杂合体作为主要产物，SubPc-O-Pc-O-SubPc 三合体作为次要副产物。两者的吸收光谱都显示了配体存在的主要特征，这意味着激子耦合是有限的。1 与轴向羟基、轴向甲基硅酞菁的进一步反应提供了一个关键的 Pc-O-Pc′ 二元化合物，该化合物被证明是一种理想的中间体，可用于开发合成策略，以获得一系列杂金属类/杂配体 Pc-O-Pc′-O-Pn 三元化合物。本文讨论了这些阵列实例的 X 射线结构数据。三元化合物的一个特点是它们的吸收光谱波段非常宽，从紫外波段到可见光波段一直延伸到近红外波段。

  Defined face-to-face structures of phthalocyanine and porphyrin chromophores can be prepared using a modular strategy that allows directional, stepwise construction. μ-Oxo linkage between the central group of 14 metalloid atoms Si and Ge ensures π-overlap between the macrocycles, and exciton coupling effects further extend the absorption profile to provide arrays that absorb across the whole UV−visible

  可以使用允许定向，逐步构建的模块化策略来制备定义的酞菁和卟啉生色团的面对面结构。14个准金属原子Si和Ge的中心基团之间的μ氧键确保大环之间的π重叠，并且激子耦合效应进一步扩展了吸收谱，从而提供了可吸收整个UV可见光谱并吸收到近IR的阵列。 。该策略具有足够的通用性，可以扩展到更高定义的低聚物的合成以及随后在堆栈的一个或两个末端上的官能化或连接。
