Surface-enhanced infrared absorption (SEIRA) experiments revealed that the chain length and evaporation rate of alkane deposition solvents altered 4-fluorobenzoic acid (4FBA) adsorption. 4FBA did not dissociate in the multilayer with the fast-evaporating n-pentane deposition solvent. However, with n-hexane and heavier solvents, the evaporation rate was slow enough to allow significant formation of 4-fluorobenzoate ions (4FBI) in the multilayer. Strong intermolecular attractions were present with heavier deposition solvents as evidenced by the incorporation of n-heptane into the 4FBI multilayer. This work will apply to many synthetic, biological, and environmental areas involving the interaction of metal nanostructures with oxygenated or halogenated hydrocarbons.

烷烃沉积溶剂的选择对银纳米结构上吸附的4-氟苯甲酸层的影响

表面增强红外吸收（SEIRA）实验表明，烷烃沉积溶剂的链长和蒸发速率改变了4-氟苯甲酸（4FBA）的吸附。4FBA没有与快速蒸发的正戊烷沉积溶剂在多层中解离。然而，随着Ñ正己烷和较重的溶剂中，蒸发速度慢到足以允许4-氟离子（4FBI）在多层的显著形成。较重的沉积溶剂具有很强的分子间吸引力，这可以通过结合使用n来证明。庚烷进入4FBI多层膜。这项工作将适用于涉及金属纳米结构与氧化或卤代烃相互作用的许多合成，生物学和环境领域。
