Abstract The synthesis and characterization of some new peripherally substituted Cu-pyrazinoporphyrazines (Cu-Pzs) is described. The prepared α-dicyano compounds in the presence of cuprouschloride produced porphyrazine counterparts via one-pot cyclotetramerization reaction. The resulted porphyrazines are useful photosensitizers and good reagent for photodynamic therapy of cancer.

Bromination of 2,7-dinitro-9,10-phenanthrenequinone, 2,5-dinitro-9,10-phenanthrenequinone, and 2,4,7-trinitrofluorenone with bromine in concentrated sulfuric acid in the presence of acetic acid gave, respectively, 4-bromo-2,7-dinitro-9,10-phenanthrenequinone, 2-bromo-4,7-dinitro-9,10-phenanthrenequinone, and 5-bromo-2,4,7-trinitrofluorenone. No bromination occurred in the absence of nitric acid. The

Phenanthrenequinone monoxime and its mono-, di-, and trinitro derivatives were synthesized. The acidity constants and their variation with the number and position of nitro groups were determined. The electronic and IR spectra of the nitro compounds were studied. The bands in the electronic spectra were assigned based on quantum-chemical calculations in the Pariser—Parr—Pople approximation.

[A–D] complexes, HOMO and LUMO gaps in CTC are found by quantum chemical calculations, and they correlate with the experimental positions of long-wave bands in the electron absorption spectra of the complexes in solutions. The crystal and molecular structures of new 1:1 CTC of 2,4,7-trinitro-9,10-phenanthrenequinone with anthracene is determined by single crystal X-ray diffraction. In crystal, CTC has
