Adlayers were formed on self-assembled monolayers (SAMs) formed by alkanethiols on gold. Base SAMs exposing amide functional groups at the SAM surface were formed with 12-mercaptododecanamide. Adlayers of diacetylene-containing monomers were then formed via amide hydrogen bonding in decalin and decalin/toluene mixtures. Grazing angle FTIR, contact angle measurements, and ellipsometry suggest that these adlayer films exhibit ordering and packing similar to that of SAMs on gold. Resonance Raman spectroscopy showed that these diacetylene adlayers could be readily polymerized by exposure to UV light.
在由烷硫醇在金表面形成的自组装单分子层（SAMs）上形成了附加层。用12-巯基十二烷酰胺形成在SAM表面暴露酰胺官能团的基础SAMs。然后通过在萘烷和萘烷/甲苯混合物中的酰胺氢键作用形成含二乙炔的单体附加层。掠角傅里叶变换红外光谱、接触角测量和椭偏测量表明，这些附加层薄膜表现出与金表面SAMs相似的有序性和堆积。共振拉曼光谱表明，这些二乙炔附加层通过紫外光照射可以很容易地聚合。
