N-quaternary derivatives of the diaryloxazole scintillators POPOP and dimethyl-POPOP (dmPOPOP) in chloroform solution were obtained by methylation with dimethylsulfate. After drying, aqueous solutions of the corresponding oxazolium compounds (Q-POPOP and Q-dmPOPOP) revealed strong fluorescence (peaks at 485 and 493 nm
