In this study, we attempted to regulate the intermolecular distance of PNTP molecules on the surface of silver foil by breaking the S–S bond of NPDS. Though changing the laser wavelength and power, SERS conditions, the Raman spectra of NPDS and PNTP with different concentrations were compared. We found that, under SERS conditions, NPDS converted more efficiently than PNTP to DMAB at low-concentration with low-power and low-energy irradiation. The results indicate that the distance between molecules plays a significant role in the reaction of PNTP to form DMAB.

对硝基苯二硫化物的距离调控表面等离激元催化偶联反应

在这项研究中,我们试图通过打破 NPDS 的 S-S 键来调节银箔表面 PNTP 分子的分子间距离。通过改变激光波长和功率、SERS条件,比较了不同浓度的NPDS和PNTP的拉曼光谱。我们发现,在 SERS 条件下,在低浓度、低功率和低能量辐照下,NPDS 比 PNTP 更有效地转化为 DMAB。结果表明分子之间的距离在PNTP形成DMAB的反应中起重要作用。
