Three axially bromo-substituted subphthalocyanines(SubPc) were synthesized by reacting phthalodinitriles with boron tribromide. They have very good solubility in many common organic solvents. Their electronic absorption spectra and fluorescence emission spectra were measured. These SubPcs have a maximum absorption at 570 nm, which are blue-shifted about 100 nm compared with corresponding phthalocyanine. When U-position substituent is -OCH₂C(CH₃)₃, the SubPc(2b) has fluorescence emission peaks at 415 and 608 nm. However, when there are two substituents at T-position, the SubPc(2c) has only one fluorescence emission peak at 435 nm.
