Magnesium(II)-porphyrazine (4) was prepared via a Mg-butoxide templated macrocyclization of 2,3-dicyano-6,7-dibutylthiotetrathiafulvalene in buthanol,and then 4 was converted to metal-free porphyrazine (5) by treatment with trifluoroacetic acid in the dark.5 reacted with excess zinc acetate to give zinc(II)-porphyrazine (6) in the chlorobenzene.Their structure has been characterized by 1H NMR,MALDI-TOF-MASS,UV-VIS,ESR and EA,and self-assembly behavior of 4 was studied with the help of TEM and DLS data.4 self-assembled to spherical aggregates in toluene.
