for causing the binding‐induced disassembly, be lipophilic. Demonstration of binding with lipophilicligands greatly expands the repertoire of binding‐induced disassembly, since this covers a rather large class of ligand moieties designed for proteins and these provide specific insights into the mechanistic pathways that are available for the binding‐induced disassembly process. Here, we describe the
对蛋白质存在作出反应的超分子纳米组件引起了人们极大的兴趣,因为蛋白质浓度的畸变代表了在患病状态下发现的主要不平衡。我们在此介绍了对蛋白质、免疫球蛋白 G 的存在作出反应的面部两亲性树枝状聚合物的分子设计、合成和研究。 特别令人感兴趣的是,用于引起结合诱导分解的配体功能是亲脂性的。与亲脂性配体结合的证明极大地扩展了结合诱导分解的全部内容,因为这涵盖了相当大类为蛋白质设计的配体部分,这些配体部分提供了对结合诱导分解过程可用的机制途径的具体见解。这里,

Disassembling a supramolecularassembly and releasing the contents of the assembly in response to a stimulus are important goals of supramolecular chemistry. When proteins are used as the stimulus, the biological relevance of the supramolecular event dramatically increases. Although there have been efforts in which such disassembly has been achieved using enzymatic action, such events based on ligand-receptor
Supramoleculardisassembly: Phototriggered release of noncovalently sequestered lipophilic guest molecules from dendritic supramolecularassemblies has been demonstrated. Facially amphiphilic dendrimers have been shown to provide a unique opportunity to fine‐tune the release kinetics of the guest molecules in response to light (see picture).

An amphiphilic nanoassembly was designed to respond to the concurrent presence of a protein and an enzyme. We present herein a system, where in the presence of these two stimuli supramolecular disassembly and molecular release occur. This molecular release arises in the form a fluorescence response that has been shown to be specific. We also show that this system can be modified to respond only if light stimulus is also present in addition to the protein and the enzyme. Demonstration of such supramolecular disassembly principles could have broad implications in a variety of biological applications.

interactions were found to greatly influence the temperature-dependent dynamic behavior within supramolecularassemblies. Using an amphiphilic dendron, we systematically changed the hydrophobic groups introducing increasing levels of aromaticity while keeping the hydrophilic part constant. We show that the supramolecularassemblies become less sensitive to temperature changes when aromatic interactions in
