kind of magic: Hydroxy pentaaryl borazine molecules self‐assemble into small clusters (see structure) on Cu(111) surfaces, whereas with symmetric hexaaryl borazine molecules large islands are obtained. Simulations indicate that the observed “magic” cluster sizes result from long‐range repulsive Coulomb forces arising from the deprotonation of the BOH groups of the hydroxy pentaaryl borazine.
这是一种魔术:羟基五芳基硼嗪分子在Cu(111)表面上自组装成小的簇(请参见结构),而对称的六芳基硼嗪分子则获得大岛。模拟表明,所观察到的“魔力”簇大小导致长范围从B的去质子化产生的排斥力库仑力羟基pentaaryl环硼氮烷的基团OH。
