采用热网沉积（HMD）的新方法，研究了加热钨从并五苯自下而上形成纳米石墨烯的指导方针。在该方法中，在并五苯源和石英衬底之间设置了加热W网格。并戊二烯分子通过加热W网进行分解。然后将生成的五苯基分解前驱体沉积在石英衬底上。以并五苯为原料，采用两种加热催化剂，用HMD法合成了并五苯二聚体（邻并五苯）。根据文献中密度泛函理论的计算，证实了并五烯与6,13-二氢并五烯可以反应形成并五烯二聚体。该技术可用于在无金属催化剂的情况下，在各种基质上制备新型纳米石墨烯。
The guidelines for a bottom-up approach of nanographene formation from pentacene using heated tungsten were investigated using a novel method called hot mesh deposition (HMD). In this method, a heated W mesh was set between a pentacene source and a quartz substrate. Pentacene molecules were decomposed by the heated W mesh. The generated pentacene-based decomposed precursors were then deposited on the quartz substrate. The pentacene dimer (peripentacene) was obtained from pentacene by HMD using two heated catalysts. As expected from the calculation with the density functional theory in the literature, it was confirmed that the pentacene dimer can be formed by a reaction between pentacene and 6,13-dihydropentacene. This technique can be applied to the formation of novel nanographene on various substrates without metal catalysts.
