In an effort to develop safe and potent anti-inflammatory agents, a series of novel 4′-fluoro-2′-hydroxychalcones 5a-d and their dihydropyrazole derivatives 6a-d was prepared. It was synthesized via aldol condensation of 4′-fluoro-2′-hydroxyacetophenone w

A difluorosubstituted aza-boron-dipyrromethene derivative with fully chelated boron atom was synthesized by the reaction of BF3Et 2O with 3,3,5,5-tetraarylazadipyrromethene, which was easily prepared from 1,3-diaryl-4-nitro-butan-1-one and ammonium acetate. One fluorine atom of the dye was substituted by pyrrolidine residue. This resulted in a significant bathochromic effect. Ultraviolet absorption and fluorescence emission spectra were recorded, and quantum yields of the obtained compounds were calculated.
