Efficient direct synthesis of new monomeric and stable J-type dimeric species of 2-hydroxy-9(10),16(17),23(24)-tri-tert-butylphthalocyaninato aluminum with high yields, including preparation of the corresponding dimeric free-base ligand at ambient conditions, has been developed. The compounds were characterized by the UV–Vis spectroscopy as well as MALDI-TOF mass-spectrometry and thermogravimetry...
A quadruple-decker sandwich complex of lutetium (III) based on a clamshell-type phthalocyanine ligand has been obtained in a high yield (90%). The obtained compound was characterized by a combination of high resolution MALDI TOF/TOF mass spectrometry, UV–Vis–NIR, EPR and 1H NMR spectroscopies. An investigation of the absorption spectrum in the NIR region showed maxima at 918 nm and in the 1260–1520 nm...
