In recent years, phospholes emerged as photoluminescent materials and offer special properties useful for the development of devices in the area of molecular electronics. In this project we propose a synthetic access to a novel type of phospholes carrying silyl substituents in the beta-position of the phosphole system. The silyl units are intended to modulate the electronic situation of the phosphole and furthermore may serve as anchoring units for the attachment of the chromophores on surfaces. It is intended to attach phosphole units not only to macroscopic surfaces but also to oxide nanoparticles and POSS cages to investigate the interaction of the chromophores among each other. The attachment under mild conditions in an orderly fashion should allow to get insights into the properties of these chromophores at the solid interface. Ultimately, the results of this fundamental research may open the way to the discovery of novel materials and devices with low-energy excitation barriers on a long term base.

近年来，磷光体作为一种光致发光材料出现，并提供了特殊的性质，在分子电子学领域的器件的发展。在这个项目中，我们提出了一个合成途径，以一种新型的磷杂环戊二烯携带甲硅烷基取代基的β-位置的磷杂环戊二烯系统。甲硅烷基单元旨在调节磷杂环戊二烯的电子状态，并且还可以用作将发色团附着在表面上的锚定单元。它的目的是将磷杂环戊二烯单元不仅宏观表面，但也氧化物纳米粒子和POSS笼研究发色团之间的相互作用。在温和的条件下，以有序的方式连接，应该允许洞察这些发色团在固体界面的性质。最终，这项基础研究的结果可能为长期发现具有低能激发势垒的新型材料和器件开辟道路。
