在这里，我们研究并五苯薄膜在石英（0001）表面的生长。并五苯薄膜的光学性质的演变已被监测原位的光学光谱和薄膜的形貌进行了研究，非原位原子力光谱。我们发现，（001）取向的薄膜相并五苯微晶生长在一个单层厚的界面层。的光学和结构特性的第一单层确定原位和异位，分别，从那些的多层膜有很大的不同。最重要的是，当界面在随后的并五苯薄膜形成过程中被掩埋时，第一单层的独特光学性质得以保留。
Here we investigate the growth of the pentacene thin film on the quartz (0001) surface. The evolution of the optical properties of the pentacene thin film has been monitored in situ by optical spectroscopy and the thin-film morphology was investigated ex situ by atomic force spectroscopy. We find that (001)-oriented thin-film phase pentacene crystallites grow on a one-monolayer-thick interfacial layer. The optical and structural properties of the first monolayer determined in situ and ex situ, respectively, differ substantially from those of the multilayers. Most importantly, the distinct optical properties of the first monolayer are preserved when the interface becomes buried during the subsequent pentacene thin-film formation.
