  Self-Sorting of Guests and Hard Blocks in Bisurea-Based Thermoplastic Elastomers

  摘要：

  Self-sorting in thermoplastic elastomers was studied using bisurea-based thermoplastic elastomers (TPEs) which are known to form hard blocks via hierarchical aggregation of bisurea segments into ribbons and of ribbons into fibers. Self-sorting of different bisurea hard blocks in mixtures of polymers to give separate ribbons was established by studying exciplex formation between fluorescent pyrene and dimethylaniline (DMA) functionalized bisurea probes. If both probes had the same spacing between the bisurea units as the matrix hard segments, exciplex bands were observed in the fluorescence emission spectra, whereas exciplex intensities were strongly reduced when DMA and pyrene probes with different spacer lengths were incorporated in a mixed matrix that provided matching host segments for each guest separately. Probes with butylene spaced bisurea groups showed the highest degree of self-sorting. Self-sorting was further improved by annealing of the polymer films leading to a degree of self-sorting of more than 95%. Self-sorting at the fiber level of aggregation was studied by fluorescence resonance energy transfer (FRET) between naphthalene (donor)and pyrene (acceptor) bisurea guests. Large differences in FRET behavior for matching and nonmatching probes showed that significant self-sorting takes places between ribbons to give separate fibers.

  方案 1. 荧光化学传感器 1 的合成路线 杯[4]芳烃是超分子化学的重要组成部分。杯芳烃框架提供了一种独特的可能性，可以将多个结合位点组织成与潜在客体互补的阵列。在过去的十年中，已经合成了多种基于杯芳烃的阳离子、阴离子和中性分子受体。尽管阴离子识别似乎是一个相对较新的研究领域，但在过去几年中已经制备了阴离子物质的带正电和中性受体。作为荧光单元，芘是最有用的单元之一，因为它们具有相对有效的准分子形成和发射。由于准分子与单体发射的强度比 (IE/IM) 对芘附加受体的构象变化敏感，金属离子络合后 IE/IM 的变化可以作为各种传感系统中的信息参数。双位受体同时结合阳离子和阴离子客体是离子对识别环境和生物学重要性的一个快速发展的新领域。利用杯芳烃骨架，开发了一些中性双功能受体，并在有机介质中表现出亲水性阴离子和阳离子的同时络合特性。然而，这些受体仅集中在杯[4]芳烃的锥形构象异构体上。众所周知

  Multiple, coexisting hydrophobic compartments have been created in water using molecular self-sorting among mixtures of bolaamphiphiles with differently spaced urea groups in their hydrophobic parts. The selective incorporation of bisurea functionalized fluorescent probes showed that different bolaamphiphiles form separate populations of rod-like micelles, which dynamically coexist in solution, each micelle binding to its correspondingly functionalized guests.

  The invention relates to adamantane bisurea derivatives and their use. Adamantane bisurea derivatives are obtained by reaction of adamantane diamine with appropriate isocyanate, or by in situ preparation of adamantane isocyanate from adamantane diacid and subsequent reaction with the appropriate amine. Adamantane bisureas bind the following anions: F-, Cl-, Br-, acetate, HSO4- NO3-, and H2PO4-, and particularly F- and H2PO4-. The presence of anions can be detected by UV -vis or fluorescence spectroscopy. Formula (I).
