Abstract

Although aurophilicity is a well-known phenomenon in structural gold chemistry and is found in many crystals of Au(I) complexes, its potential for self-assembly in thin films is not yet explored. This paper is Part II of a study, in which we investigated the ultrathin film formation of chlorido(2-naphthyl isonitrile) gold(I) on gold surfaces. Here, we present the data for the growth of (NapNC)AuCl on isotropic Au(111) surfaces. Already during physical vapor deposition, the condensation of ultrathin films is monitored by photoelectron emission microscopy (PEEM) and incremental and spectrally resolved changes in the optical reflectance (DDRS). Additional structural data obtained by scanning tunneling microscopy (STM) and low-energy electron diffraction (LEED) reveal that the "crossed swords" packing motif known from the bulk is also present in thin films.

摘要

尽管亲金性在结构金化学中是一个广为人知的现象，并且在许多Au(I)配合物晶体中都能发现，但它在薄膜中自组装的潜力尚未得到探索。本文是一项研究的第二部分，在该研究中我们研究了氯代(2-萘基异腈)金(I)在金表面形成超薄膜的情况。在此，我们展示了(NapNC)AuCl在各向同性Au(111)表面生长的数据。在物理气相沉积过程中，通过光电子发射显微镜(PEEM)以及光学反射率的增量和光谱分辨变化(DDRS)来监测超薄膜的凝聚。通过扫描隧道显微镜(STM)和低能电子衍射(LEED)获得的其他结构数据表明，从块体中已知的“交叉剑”堆积 motif 在薄膜中也存在。
