Abstract

Detection and quantification of submonolayer coverage surface species is not trivial. We have developed a novel method sensitive to surface-bound chemical functional groups as low as 10(11) molecules/cm(2) by specific covalent attachment of fluorescent chromophores. This enables the intermediates of the UV photochemistry of alkylsiloxane self-assembled monolayers to be identified.

摘要

检测和定量亚单层覆盖的表面物种并非易事。我们开发了一种新方法，通过荧光发色团的特异性共价连接，对低至10(11)个分子/平方厘米的表面结合化学官能团敏感。这使得能够识别烷基硅氧烷自组装单分子层的紫外光化学中间体。
