DABCO cadmium(II) tetrakis(4-metoxyphenyl)porphyrin complex – Structure, photophysical properties, and adsorpion removal of methylene blue dye

In this work, a new cadmium(II) complex namely the (1,4-diazabicyclo[2.2.2]octane)(meso-tetrakis(4-tert-methoxyphenyl)porphyrinato)cadmium(II) with formula [Cd(TMPP)(DABCO)] (I) (DABCO = 1,4-diazabicyclo[2.2.2]octane) was successfully synthetized. The structure of have been characterized by FT-IR, 1HNMR, UV–visible, fluorescence spectroscopies and single crystal X-ray diffraction technique. DFT calculations has made for structural, 1H NMR spectroscopy IR spectra analysis. adsorption methylene blue (MB) dye studied to examine efficiently removing cationic dyes from aqueous solution. Langmuir capacity (Q0max) at 290 K pH 7.0 found be 69.24 mg.g?1. mechanism which involved ?-? interaction between MB molecule porphyrin ring is well described pseudo second-order Elovich models.
