Tetrakis(ethyl-4(4-butyryl)oxyphenyl)porphyrinato zinc complexes with 4,4'-bpyridin: synthesis, characterization, and its catalytic degradation of Calmagite.
This work reports on the synthesis and characterization of a new porphyrins complex:[Zn(TEBOP)(4,4'-bpy)](4,4'-bipyridine)(5,10,15,20-(tetraethyl-4(4-butyryl)oxyphenyl)porphyrinato)zinc(II) (3). Single crystal X-ray diffraction, photophys. and electrochem. characteristics were studied. The prepd. complex, penta-coordinated zinc(II) porphyrin derivs. shows moderate ruffling distortion and the zinc atom is nearly planar with the porphyrin core. Tolyl and ethyl-4(4-butyryl)oxyphenyl) moieties at the meso positions present a bathochromic shift of the absorption bands, and a notable increase in the absorption coeff. of the Q(0,0) and Q(0,1) bands was obsd. with a higher fluorescence quantum yield and lifetime compared with the free base porphyrin. The electrochem. investigation shows a reversible redn. of the synthesized complexes. The catalytic power and the adsorption properties of the prepd. complexes were studied for Calmagite degrdn., an azoic org. dye. The results reveal that the studied compds. could be used as catalysts for the decolorisation of dyes in the presence of H2O2. [on SciFinder(R)]
