Abstract A series of thiaphlorins with N 2 S 2 and N 3 S cores have been prepared in decent yields from readily available precursors. The thiaphlorins were characterized by all spectroscopic techniques and the structures of two thiaphlorins were solved by X-ray crystallography. The spectral studies indicated that the properties of thiaphlorins were quite different from those of thiaporphyrins. The methodology used for the synthesis of ...
