Abstract Two novel A2B type free-base corroles， 10-(2,6-dichlorophenyl)-5,15-bis(3-nitro-phenyl)-corrole(3a) and 10-(2,6-difluorophenyl)-5,15-bis(3-nitrophenyl)-corrole(3b), were synthesized by acid-catalyzed coupling reaction and then oxidation, using m-nitrophenyl dipyrromethane and 2,6-dichlorobenzaldehyde or 2,6-difluorobenzaldehyde as materials. The structures were characterized by 1H NMR, 13C NMR, IR and MALDI-TOF-MS. The optical properties of 3a and 3b were investigated by UV-Vis and fluorescence. Ｔhe results showed that λmax of 3 were around 414 nm, 575 nm, 610 nm and 642 nm, and λem were around 661 nm(λex=430 nm)。
