一般描述
1-十八烷硫醇（ODT）是一种具有18碳烷基链的水溶性硫化合物，它与过渡金属（如金）形成强疏水性组装体，并在此类过渡金属表面形成自组装单层（SAM）。硫醇膜与金属电极表面共价键合时，显示出电致伸缩现象，导致电容变化。ODT SAM具有疏水表面，接触角为102oC。
应用
ODT用于将硫醇化分子沉积到金基质的表面上，例如
- 金石英晶体谐振器上的SAM。
- 在原子力显微镜探针的尖端。
- 电容式传感器。
分析说明
熔化时可能含有沉淀

A sample preparation method that combines a modified target plate with a nanoscale reversed-phase column (nanocolumn) was developed for detection of neuropeptides by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). A gold-coated MALDI plate was modified with an octadecanethiol

We report studies on surface modification of graphene with 1-octadecanethiol and its application as heavy metal sensors. The alkanethiol molecules can self-assemble into large-scale highly ordered monolayers on single-layer graphene regardless of the roughness of graphene surfaces inherited from the
