英语翻译
The DIP molecules adsorbed at the step edges align their long molecular axis parallel to the step direction and consequently form rows in a head-to-tail configuration.In contrast,the adsorption at the reconstruction elbows does not give clear evidence of any preferred molecular orientation.Upon further growth of the nuclei,no order is developed among the molecules.This is a signature of the low intermolecular interactions,as expected from the absence of functional groups with the potential to form H-bonds or give rise to any other interactions stronger than the van der Waals contribution.Only in large DIP assemblies extending over more than 100 nm2 do
we find a long range ordered structure.A discrete number of rotational domains is observed,evidencing the role of the substrate as template directing the molecular ordering.Interestingly,the different domains are not separated by abrupt boundaries but often follow a gradual transition among the different orientations.This can

答案

的DIP的一步边缘吸附分子,使它们长期平行步骤分子轴方向,从而形成的行头对尾配置.相反,在重建肘部吸附没有给予任何优先分子取向的明确证据.在完成核的进一步发展,没有秩序是发达国家之间的分子.这是一个低分子间相互作用的签名,因为从有可能形成氢键或引起任何比范德华贡献其他互动功能更强的组织的情况下预期.只有在大倾角装配了100多nm2延长做
我们发现还有一项长程有序结构.旋转域的独立的一些观察,证明作为底物作用的分子模板指导订购.有趣的是,不同的域分隔突然没有国界,但往往走在不同的方向逐步过渡.这可以看出图
