A wide band of visible light absorption of three triplet photosensitizers based on, it has the following structure: compared with the prior art, the significant advantages are: Rh C key through the axial connection of the rhodium porphyrin synthesis aza fluorboric two pyrrole {Rh (TTP) aza BODIPY} compounds. The design and synthesis of the one hand can make the d orbital of metal as the frontier orbitals participate in electronic transition and transfer process, increase the intersystem crossing, improve the efficiency at the same time, three states, two fluorescent molecular absorption spectra of organic combination, obtained in the whole visible spectrum of three triplet photosensitizers with strong absorption wide. The synthesis design is not limited by many factors of resonance energy transfer, and the operation is simple and flexible. The three triplet absorption spectra of synthetic photosensitizer 750nm coverage from 380nm, regardless of any wavelength of the absorption spectrum excitation can effectively generate singlet oxygen, so the photosensitizer can efficiently use composite light energy, such as sunlight, the superior performance so that it has a good application prospect. The invention discloses a method for making the same.
