In this paper,2D asynchronous spectra generated by using the DAOSD approach was utilized to probe interactions between Nd~(3+) and pyridinium dissolved in aqueous solution.A series of cross peaks in the resultant 2D asynchronous spectrum confirms the occurrence of intermolecular interaction between Nd~(3+)and pyridinium.However,no coordination occurs between Nd~(3+) and pyridinium.Interaction between πelectron from aromatic system and/electron from lanthanide ions account for the appearance of cross peaks in 2D asynchronous spectra.Because of the interaction,the emission spectrum of pyridinium exhibits a significant change when neodymium perchlorate was introduced into the system.
