Direct comparison of SnPc growth on a metal and a nearly insulating surface was achieved by adsorption of SnPc on Au(111) partially covered with NaCl. While on Au(111), SnPc lies flat and grows in a Stranski-Krastanov mode; on NaCl, Volmer-Weber growth of three-dimensional molecular nanocrystals occurs. On NaCl, intermolecular interactions dominate over the molecule-NaCl coupling and result in a tilted adsorption configuration.
通过将 SnPc 吸附在部分被 NaCl 覆盖的 Au(111)上，实现了 SnPc 在金属和近乎绝缘表面上的直接比较。在 Au(111)上，SnPc 平躺并以 Stranski-Krastanov 模式生长；在 NaCl 上，发生了三维分子纳米晶体的 Volmer-Weber 生长。在 NaCl 上，分子间相互作用超过了分子-NaCl 耦合，导致倾斜的吸附构型。
