Molecular Complexation between Iodine(III) Chloride and Meso‐tetraarylporphrins: Synthesis, Spectroscopic Characterization and Photoluminescence Study

Abstract

Iodine(III) chloride and free base para-substituted meso-tetraarylporphyrins (H 2 t(4-Xp)p, X = OCH 3 , CH 3 , CH(CH) 3 , H, Cl) react at mild conditions for formation of [(ICl 3 )H 2 t(4-Xp)p] molecular complexes. The very close correspondence between the UV-VIS and ( 1 H, 13 C) NMR spectra of these complexes and molecular complexes of porphyrins with various acceptors indicated that two lone pairs of the pyrrolenine nitrogens in the tilted porphyrin macrocycle bonded to an iodine(III) center of ICl 3 .

Spectrophotometric Determination of Kinetic Constants of Fe (III)-Amines’s Charge Transfere Complexes

“…[1][2][3][4][5][6] Generally, these complexes were obtained by using different electron donors with various organic, [7][8][9][10] or metallic electron acceptors [11][12][13] in polar and non-polar solvents. In this work, the formation of complexes were discussed and different parameters concerning their behaviour in methanol solution at 25°C were calculated.…”
