Molecular Fragments of Heteroatom-Doped Carbon Allotropes by Chemical Synthesis (A05)

该项目侧重于合成结构上和电子上复杂的多环芳烃，包括6元苯环，各种杂原子以及不同大小的环部分选择性嵌入sp2-碳框架内。通过在溶液、表面或气相中进行不同的合成方法，精心设计的前体分子可以获得对大小、形状和边缘结构具有高度控制的目标结构。所得到的化合物将进行全面的跨学科研究，以揭示杂原子与非苯环结合对光电和材料特性的影响，从而在杂原子掺杂碳同素异形体和富碳化合物领域产生新的知识，并确定最有可能作为有机功能材料应用的候选化合物。

The project focuses on the synthesis of structurally and electronically complex PAHs comprising next to 6-membered benzenoid rings various heteroatoms together with cyclic moieties of different sizes selectively embedded within the sp2-carbon framework. The target structures with a high degree of control over the size, shape, and edge structure will become accessible from carefully designed precursor molecules through different synthetic methodologies carried out either in solution, on surfaces, or in the gas phase. The resulting compounds will be subjected to comprehensive interdisciplinary studies to unravel the impact of the heteroatoms in combination with non-benzenoid rings on the optoelectronic and materials features in order to generate new knowledge in the field of heteroatom-doped carbon allotropes and carbon-rich compounds and to identify the most promising candidates for potential application as organic functional materials.
