Abstract—The kinetics of formation of zinc complexes with 5,10,15,20-tetra(4-Cl-phenyl)porphine and 5,10,15,20-tetra(4-NH2-phenyl)porphine in acetonitrile in the range of 298–318 K are studied. It is found that peripheral substituents in tetraphenylporphine can slow down or accelerate the reaction of formation of zinc complexes in acetonitrile as observed by changes in kinetic rate constants. The fluorescence quantum yields of tetraphenylporphine derivatives and their zinc complexes also depend on the presence of electron-donating or electron-drawing substituents in the ligand structure.
