Abstract
New highly stable benzo-fused m-trifluoromethylphenyl porphyrazines and their complexes with Mg and In were synthesized by cross-condensation of phthalonitrile and bis(m-trifluoromethylphenyl)fumaronitrile. Their 1H and 13C NMR spectra were recorded and described. The Q- and B-bands in the UV/Vis spectra of the metal complexes show the characteristic splitting upon consecutive benzo-annulation. The strong variation of spectral features upon benzo-fusing and metallation/demetallation, as well as the good solubility of the metal complexes in organic solvents, make these materials potentially valuable for optical applications including nonlinear optics.
