  The Effect of Intermolecular Hydrogen Bonding on the Fluorescence of a Bimetallic Platinum Complex

  摘要：

  The bimetallic platinum complexes are known as unique building blocks and arewidely utilized in the coordination-driven self-assembly of functionalized supramolecular metallacycles. Hence, photophysical study of the bimetallic platinum complexes will be very helpful for the understanding on the optical properties and further applications of coordination-driven self-assembled supramolecular metallacycles. Herein, we report steady-state and time-resolved spectroscopic experiments as well as quantum chemistry calculations to investigate the significant intermolecular hydrogen bonding effects on the intramolecular charge transfer (ICT) fluorescence of a bimetallic platinum compound 4,4'-bis(trans-Pt(PEt3)(2)OTf)benzophenone 3 in solution. We demonstrated that the fluorescent state of compound 3 can be assigned as a metal-to-ligand charge transfer (MLCT) state. Moreover, it was observed that the formation of intermolecular hydrogen bonds can effectively lengthen the fluorescence lifetime of 3 in alcoholic solvents compared with that in hexane solvent. At the same time, the electronically excited states of 3 in solution are definitely changed by intermolecular hydrogen bonding interactions. As a consequence, we propose a new fluorescence modulation mechanism by hydrogen bonding to explain different fluorescence emissions of 3 in hydrogen-bonding solvents and nonhydrogen-bonding solvents.

  10-distyrylanthracene (DSA) were constructed herein via the design of DSA moieties on the inside or outside of metallacycles. Similar building blocks of the two metallacycles led to the same emission wavelengths in a dilute solution. In contrast, their fluorescence emissions in the aggregation and solid states were significantly different and revealed interesting emission behaviors from structures with inner-

  为了完全揭示内外改性金属环的结构和发光特性之间的关系，两个菱形金属环S1和S2本文通过在金属环内部或外部设计 DSA 部分构建了具有 9,10-二苯乙烯基蒽 (DSA) 的化合物。两种金属环的相似结构单元在稀溶液中产生相同的发射波长。相比之下，它们在聚集态和固态下的荧光发射明显不同，并揭示了具有内部和外部改性设计的结构的有趣发射行为。最后，基于它们的发光特性，将两种超分子以不同的比例混合，很容易得到一种可调谐的固态荧光发射材料。

  在超分子组件中组织分子马达以允许运动和集体行动的放大和传输，是迈向未来响应系统的重要一步。金属配位驱动的定向自组装成超分子金属环提供了一种强大的策略，可以将几个运动单元定位在具有明确几何形状的较大结构中。在此，我们提出了一种吡啶基修饰的分子马达配体 (MPY)，它与几何上不同的 di-Pt(II) 受体配合，组装成不同大小和形状的离散金属环。这种协调导致分子马达的吸收带发生红移，使这些机动金属环对可见光做出响应。光化学和热异构化实验表明，金属环中电机的光驱动旋转与溶液中的游离 MPY 相似。CD 研究表明，与旋转循环中每个异构化步骤相关的螺旋度反转都得以保留。为了探索集体运动，通过多重静电相互作用将含有三聚体马达的金属环与肝素聚合，以构建多组分分层系统。SEM、TEM 和 DLS 测量表明，光响应和热响应的分子运动单元能够在不解离初级金属环结构的情况下选择性地操纵二级超分子聚集过程。这些可

  recent past years, investigation of hierarchical self-assembly for constructing artificial functional materials has attracted considerable attention. Discrete metallacycles based on coordination bonds have proven to be valid scaffolds to fabricate various supramolecular polymers or smart soft matter through hierarchical self-assembly. Here, we present the first example of the hierarchical self-assembly

  近年来，用于构建人工功能材料的分层自组装研究引起了相当大的关注。基于配位键的离散金属环已被证明是通过分层自组装制造各种超分子聚合物或智能软物质的有效支架。在这里，我们通过多重静电相互作用利用有机铂（II）金属环骨架的正电荷，展示了离散金属环分层自组装的第一个例子。肝素是一种被广泛用作抗凝药物的硫酸化糖胺聚糖聚合物，由于存在多个负电荷，因此被选择用于诱导分层自组装。为了研究分层自组装过程，通过配位驱动的自组装将聚集诱导发射 (AIE) 活性部分四苯基乙烯 (TPE) 引入金属环中。光物理研究表明，将肝素添加到 tris-TPE 金属环溶液中会导致显着的荧光增强，这支持由多重静电相互作用驱动的金属环和肝素之间的聚集。此外，通过 SEM、TEM 和 LSCM 实验检测到，通过分层自组装获得了纠缠的珍珠项链网络。特别是，在 AFM 和 TEM 图像中观察到单个珠状链，这为带正电的金属环和带负电的肝
