The Cover Feature shows the evolution of scanning tunneling microscopy images during the cyclodehydrogenation of a polyaromatic hydrocarbon precursor sublimated onto an Au(111) surface under ultra-high vacuum. This strategy allows the on-surface preparation and study of planar large and dissymmetric starphenes that could not be prepared in solution, and may give access to families of molecular logic gates that are of interest in single-molecule electronics. More information can be found in the Full Paper by A. Jancarik, A. Gourdon, F. Moresco, and co-workers.

封面特征显示了在超高真空下升华到 Au(111) 表面上的聚芳烃前体的环化脱氢过程中扫描隧道显微镜图像的演变。这种策略允许在表面上制备和研究无法在溶液中制备的平面大和不对称星形，并且可以访问对单分子电子学感兴趣的分子逻辑门家族。更多信息可以在 A. Jancarik、A. Gourdon、F. Moresco 和同事的全文中找到。
