چکیده
|
4,4’-dithiobisbenzoic acid (dtba) is equivalent to two 4-mercaptobenzoic acid (pmba) molecules connected together after losing h+, and this bimolecular mechanism of dtba efficiently promotes the ionization reaction. under the irradiation of laser light, dtba molecules are broken to form bimolecules similar to pmba, and this kind of bimolecular coupling greatly increases the probability of binding with ag nps. also, this molecule has the carboxylic acid group, which leads to a certain sensitivity to ph. in this article, through the comparison of dtba and pmba parallel experiments, it is clear that dtba has better raman activity, higher reaction efficiency, and more stable reaction than pmba. the occurrence of this highly efficient ionization reaction under the monitoring of surface-enhanced raman spectroscopy (sers) provides a certain value for the progress of further related reactions, and it also has a wide range of applications in ph sensors and intracellular ph monitoring.
