Abstract

Layer-by-layer deposition is a widely used method for surface functionalization. It is shown here that up to 58 covalently linked molecular layers could be assembled in 20 min at room temperature on a silicon wafer by the layer-by-layer click reaction of a divalent triazolinedione and a trivalent diene. The layer growth was found to be linear. The multilayers were analyzed by ellipsometry, atomic force microscopy, and X-ray photoelectron spectroscopy.

摘要

逐层沉积是一种广泛应用于表面功能化的方法。本文表明，通过二价三唑啉二酮和三价二烯的逐层点击反应，在室温下20分钟内可在硅片上组装多达58个共价连接的分子层。发现层生长是线性的。通过椭偏仪、原子力显微镜和X射线光电子能谱对多层膜进行了分析。
