摘要：

Systems containing pyrene and tetraalkylammonium halides (R4NX) were investigated using time-resolved and steady state fluorescence techniques. The existence of a previously suggested weak interaction between pyrene and quaternary ammonium groups is confirmed and is further verified by solubility measurements. The quenching of pyrene fluorescence by R4NBr is a synergistic effect, requiring Br- and enhanced by the simultaneous presence of the quaternary ammonium ion. The presence of tetraalkylammonium halides also affects the efficiency of pyrene excimer formation.
