Abstract

The dissymmetrical and dipolar Y(III) complex 2 and its cationic precursor 1, containing the proligands 5,10,15,20-tetrakis(4-bromophenyl)porphyrin L1 and 1-anisyl-1,3-butanedione L2, were synthesized at fairly high yields, ranging from 40 to 78%, by conventional and microwave-assisted techniques, and were isolated as a microcrystalline compound. The products obtained in each case were characterized by H-1-NMR, mass spectrometry, elemental analysis, Med-IR and Far-IR. The IR information collected shows good agreement with respect to the density functional theory (DFT) calculations carried out, validating the molecular geometry in each case. This innovative one-pot microwave-based method contributes an efficient pathway for obtaining challenging molecular architectures based on monoporphyrinate complexes without Diglyme.
