  聚富勒烯-三脚架配体的光捕获超分子卟啉大环。

  摘要：

  卟啉两端带有咪唑基的Trisporphyrinatozinc（II）（1-Zn）通过咪唑基与锌（II）的互补配位而完全自组装成聚光的三聚体（N-（1-Zn）（3））。 ）。因为1-Zn中只有两个末端卟啉用于环形成，所以大环N-（1-Zn）（3）留下了三个未配位的卟啉锌（II）基团，可以将配体容纳在中心孔中。通过将三脚架配体3与吡咯烷修饰的富勒烯偶联，合成了一个通过酰胺键连接的附加富勒烯的吡啶基三脚架配体（C（60）-Tripod），并将该配体掺入N-（1-Zn）（3） 。C（60）-三脚架在苄腈中的结合常数达到10（8）M（-1）的数量级。此值是吡啶基四足配体2和三脚架配体3的十倍。此行为表明，富勒烯部分有助于增强N-（1-Zn）（3）中C（60）-Tripod的结合。通过与C（60）-Tripod的络合，N-（1-Zn）（3）的荧光几乎完全被淬灭（大约97％），而没有任何迹象表明形成电荷

  The invention relates to a method for the preparation of a coating comprising at least one coating layer on a substrate, the method comprising the steps of a. providing monomers of the type R—(N)x-(L)m-(C═C)n-(L′)o-(N′)y—R′, wherein R is a head moiety, R′ is a tail moiety, (C≡C)n is an oligoyne moiety, L and L′ are linker moieties, N and N′ independently are branched or unbranched optionally substituted C1-C25 alkyl moieties optionally containing 1 to 5 heteroatoms, x, m, o, and y are independently 0 or 1, n is 4 to 12, and wherein the head moiety allows for an interaction with the surface of the substrate; b. bringing the monomers into contact with the substrate wherein the interaction of the head moieties of the monomers with the surface of the substrate induces at least a part of the monomers to align in a defined manner thereby forming a film on the surface and bringing the oligoyne moieties of the monomers into close contact with each other; c. inducing a reaction between oligoyne moieties by providing an external stimulus so as to at least partially cross-link the aligned monomers, thereby forming a coating layer on the substrate. The invention further relates to a coating obtainable according to the method of the invention, the use of a coating obtainable according to the method of the invention, a substrate comprising a coating obtainable according to the invention and the use of solid substrate. The invention further relates to a method for the synthesis of the monomers according to the invention.

  本发明涉及一种在基底上制备包含至少一个涂层的涂层的方法，该方法包括以下步骤 a.提供R-(N)x-(L)m-(C═C)n-(L′)o-(N′)y-R′类型的单体，其中R是头部分子，R′是尾部分子，(C≡C)n是低碳原子分子，L和L′是连接分子、N和N′独立地是支链或未支链的任选取代的C1-C25烷基，任选含有1至5个杂原子，x、m、o和y独立地是0或1，n是4至12，其中头部分子允许与基质表面相互作用；b.使单体与基底接触，其中单体的头部分子与基底表面的相互作用诱导至少一部分单体以确定的方式排列，从而在表面上形成薄膜，并使单体的低聚酰亚胺分子彼此紧密接触； c. 通过提供外部刺激，诱导低聚酰亚胺分子之间发生反应，使排列的单体至少部分交联，从而在基底上形成涂层。本发明进一步涉及根据本发明方法可获得的涂层、根据本发明方法可获得的涂层的使用、包含根据本发明可获得的涂层的基底以及固体基底的使用。本发明进一步涉及根据本发明合成单体的方法。
