A facile and efficient synthesis of 14-aryl or alkyl-14H-dibenzo[a,j]xanthenes has been accomplished by treatment of -naphthol with aryl or alkyl aldehydes catalyzed by 2-1'-methylimidazolium-3-yl-1-ethyl sulfate in ionic liquid [BMIM][BF4] at 80 degrees C. The luminescence of products was studied in detail.
