indicates that SAMs of 9-alkylfluorenyl thiols 1 form well-ordered monolayers on polycrystalline gold. Sessile drop contact angle measurements demonstrate the hydrophobic nature of these self-assembled thin films. The thicknesses of the films as measured by optical ellipsometry correspond well to the calculated thickness of monolayer films in which the extended alkylchains are oriented at a 30° angle to the
光谱表征表明 9-烷基芴硫醇 1 的 SAM 在多晶金上形成有序的单分子层。固着液滴接触角测量证明了这些自组装薄膜的疏水性。通过光学椭圆光度法测量的薄膜厚度很好地对应于计算出的单层薄膜的厚度,其中延伸的烷基链与金表面成 30° 角取向。在接触的 KCl 水溶液中,这些薄膜紧密堆积并钝化了 Au 表面和 K4Fe(CN)6 之间的电子转移。掠角反射 FTIR 光谱显示芳族芴基固定在距 Au 表面的定义距离处,这由设置在全反式构象中的烷基链长度确定。当在稀溶液中测量时,与相应分子的荧光相比,SAM 的表面荧光光谱发生了红移和变宽。结合为...时末端芴基的寿命
