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.
在本研究中，我们试图通过破坏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、低功率和低能量照射下，NPDS比PNTP更有效地转化为DMAB。结果表明，分子间距离在PNTP形成DMAB的反应中起重要作用。
