| Abstract | ||
| The photochemistry of chelate complex 2-(6-methoxynaphthalen-2-yl) propanoic acid iron (III) Fe(L)3 was studied in three polar aprotic solvents: Dimethyl sulfoxide (DMSO), Dimethyl form amide (DMF), Acetone (Ac). Monochromatic light of wavelength 311 nm was utilized for the irradiation-process at 25oC. UV-VIS changes demonstrated an intraoxidation-reduction response happening amid the photolysis of Fe(L)3 complex, with homolytic scission of Fe-L bond. Quantum yield (Qd), rate of photodecomposition and reactivity proportion (k2/k-1) was resolved in every used solvent. These values dependably increment as polarity of the solvent increments and take after the order: DMSO > DMF > Ac. The mechanism of photodecomposition of this complex under the connected conditions was proposed. | ||
