Highly fluorinated arenes currently gain significant interest as n-semiconducting materials. Until today only very few basic compounds (such as perfluorotetracene and pentacene) have been synthesized, showing very promising bulk properties. In the current project, perfluoroacenes should become substituted for the first time to attach these molecules to surfaces in form of self-assembled monolayers. For this, a suitable synthetic chemistry has to be developed first. Upon variation of suitable molecular parameters (size of the acene system, length of the linking unit, possibly adjustment of the anchoring group) their influence on the structural properties of the respective SAMs shall be explored and optimized. Such monolayer systems should show interesting electronic properties and extend the possibilities in the area of molecule-based electronics, in particular regarding n-semiconduction. The respective investigations will be performed in close collaboration with partners in particular from physical chemistry.

高氟化芳烃作为n-半导体材料目前引起了人们极大的兴趣。直到今天，只有很少的碱性化合物（如全氟四烯和并五烯）被合成，显示出非常有前途的体积性质。在目前的项目中，全氟环烯将首次被取代，以自组装单层的形式将这些分子附着在表面上。为此，必须首先开发一种合适的合成化学。在适当的分子参数（烯体系的大小，连接单元的长度，可能的锚定基团的调整）变化后，探索和优化它们对各自sam结构性质的影响。这种单层系统应该显示出有趣的电子特性，并扩展了分子电子学领域的可能性，特别是在n-半导体方面。各自的调查将在与伙伴特别是物理化学伙伴的密切合作下进行。
