SYNTHESIS OF COPPER(II) COMPLEX WITH MESO -TETRA(4-HYDROXYPHENYL) PORPHYRIN BY SOLID-STATE REACTION

The metalloporphyrin coordination complex (copper with meso-tetra (4-h ydroxyphenyl) porphyrin) was synthesized by solid state reaction at ro om temperature. The molar ratio of copper acetate (Cu(Ac)(2) . H2O to T(4-HP)P is 1 : 1. The reactants are mixed and grinded in the agate mo rtar for 15 min. The reaction rate was detected by visible absorption spectra. The soret band of ligand (422 nm) disappears, after the grind ed sample is laid up for 10 h at 12 degrees C , and the soret band of complex appears at the 427 nm(the solvent is DMF). The reaction was fi nished within 1.5 h at 35 degrees C, and was completed within 30 min a t 35 degrees C by initiation of ethanol (95%). The composition and con formation of products are characterized by elementary analysis, IR, fl uorescence and DTA. Compared with the compound synthesized in liquid s tate in DMF, the composition and structure of the complex are the same .
