一般描述
4-Mercaptobenzoic acid (4-MBA), also known as 4-Carboxythiophenol or p-Mercaptobenzoic acid, is an aromatic compound used in organic synthesis. 4-MBA promotes the formation of disulfide bonds through its reactive thiol (-SH) group. The sulfur atom in the thiol group is highly nucleophilic, allowing it to attack electrophiles. facilitates the formation of diverse thiol-containing compounds. Additionally, 4-MBA serves as a ligand to form coordination complexes and is utilized for surface functionalization, particularly in creating self-assembled monolayers (SAMs) on metal surfaces.
应用
- 食品掺假检测的SERS底物：采用4-巯基苯甲酸通过生物聚合物层层组装，原位制造AuNP等离子体纸，可作为表面增强拉曼散射(SERS)基底用于食品掺假检测(Viriyakitpattana et al., 2024)。
- 磁性-等离子体纳米粒子的开发：结合激光烧蚀和溶剂热法获得磁性-等离子体纳米粒子，可用于4-巯基苯甲酸为标记分子的多波长SERS。说明纳米颗粒合成的多样性(Talaikis et al., 2023)。

Structural information on nanometer-sized gold particles has been limited, due in part to the problem of preparing homogeneous material. Here we report the crystallization and x-ray structure determination of a p-mercaptobenzoic acid (p-MBA)-protected gold nanoparticle, which comprises 102 gold atoms
