The direct injection of a 9,10-phenanthrenequinone in tetrahydrofuran solution on a Au(111) substrate in high vacuum results in the formation of metastable clusters with a non-intuitive structure. Metastable, rectangular tetramers of this molecule form in which the net molecular dipoles all orient toward the center of the cluster. This structure does not allow for additional hydrogen bonding and thus the origin of its metastability is not clear. We compare this feature to other structures observed on this surface, as well as those formed during the deposition of 9-fluorenone, which does not exhibit this anomalous clustering behavior.
在高真空环境下，将9,10 - 菲醌的四氢呋喃溶液直接注射到Au(111)衬底上，会形成具有非直观结构的亚稳团簇。该分子形成了亚稳的矩形四聚体，其中分子净偶极矩都朝向团簇中心。这种结构不允许额外的氢键形成，因此其亚稳性的起源尚不清楚。我们将此特征与在该表面观察到的其他结构以及9 - 芴酮沉积过程中形成的结构进行比较，9 - 芴酮不会表现出这种异常的团簇行为。
